Big Risks in Small Satellites
The Need for Secure Infrastructure as a Service
Harrison Caudill (firstname.lastname@example.org) – April 29, 2019
The United States relies heavily upon space-based infrastructure for everything from executing military
operations, to hailing a taxi, to determining whether or not to bring an umbrella to the theater. Sudden
loss of our orbital assets would be catastrophic to the strength of our economy, our ability to project
power[2, p20-21], and the functioning of our civil society.[3, p3][4, III] Private companies are now launching
hundreds (soon thousands) of small commoditized satellites each year as “New Space” grows. Despite
a lack of general awareness of the cybersecurity problem[2, p8], we are becoming ever more dependent
upon our space assets, and our ability to protect them is rapidly declining.[6, §7p1] While this paper focuses
on the smallsat revolution currently under way, its ﬁndings can be applied equally to most other space
The United States is ill prepared for criminal cyberattacks directed at satellite infrastructure, and
even less prepared for sophisticated state-sponsored efforts against our new constellations of privately-
owned SmallSats. There are few security measures in place, and even fewer enforced regulations to protect
these assets.[8, p5] Many regulatory recommendations being proposed, such as mandatory encryption, are
inadequate. Immediate action is necessary to address the core security challenges of the space industry.
By recognizing the immense ROI associated with a successful cyber attack we can begin to frame the
security needs in their proper context.[4, p III, 20]
This paper discusses the speciﬁc challenges associated with securing orbital assets and offers policy
recommendations to prepare us for the expansion of the space industry. It further proposes an efﬁcient
mechanism by which we can simultaneously enable market growth, ensure regulatory compliance, and
mitigate the national security issues associated with this new phase of the space industry.
The Challenges of Space Security
Assets in space are unique in that, once deployed, builders and operators are unlikely to have direct
access to the hardware again. The lack of physical access only intensiﬁes the necessity of cybersecu-
rity. Without the ability to unplug and reset the system, an intruder could potentially lock out the owners
by changing the passwords, as it were. If that happens, the asset would then belong to the attacker; the
owner would no longer have access. This threat represents an unacceptable risk to national security.[2,
p23] Nation-states and criminals alike could potentially gain immediate control of critical strategic capabil-
ities that they currently lack by hacking exposed satellites belonging to commercial entities. Worse yet,
physical access may soon be granted to adversaries as satellite-servicing technologies are developed.[9,
Recent security ﬁndings have shown that pre-existing space assets are vulnerable to attack.[6, §7p4]
Openly discussed cyberattack methods are frequently less sophisticated than those already being employed
by state actors, suggesting that America’s satellite infrastructure may already be under attack. Security
controls to combat such attacks vary wildly throughout the industry, ranging from practically non-existent,
to best-effort large commercial organizations, to highly-secured government contractors. Many current
policy recommendations meant to address vulnerabilities barely account for attack methods which have
already been demonstrated, let alone sophisticated attacks which have not been observed or disclosed.[8,
The greatest challenge to the development and deployment of appropriate security controls is the
economic viability of doing so.[2, p13] Even the minimum necessary set of security controls and policies
would likely be too much for most large companies to bear, to say nothing of small startups. Recognizing
this key requirement, the recommendations below provide an efﬁcient market-friendly solution that will not
only ensure compliance, but also encourage market growth by actually decreasing startup and operational
Strong new policies must be be developed and strictly enforced for the following:
1. Space assets relied upon by the DoD (eg. Commercial Weather)
2. Any space asset which would be of great value to an adversary if captured (eg. RADAR)
3. Anything deemed to be critical civilian infrastructure (eg. Internet of Things relays)
4. Any asset capable of being a physical threat (eg. Refueling Satellites)
The regulations necessary to provide even a minimum level of security would likely be too much for
most companies to (at least willingly) bear without assistance. In order to ensure adoption of appropriate
security standards by all market players, it is further recommended that incentives be created for two types
of Infrastructure Service Providers:
1. Mission Operations Infrastructure Services
2. Communications Infrastructure Services
Just as wireless carriers are (nominally) tasked with securing their cell-phone networks, the listed types
of Infrastructure Service Providers could ensure the existence of more secure (and more economical) al-
ternatives to the current industry practice of vertical integration. Utilization of security-hardened versions of
these services would greatly enhance the security posture of the industry while simultaneously decreasing
entry barriers and increasing reliability.
Existing space systems owned by large organizations are vulnerable, small startup companies are
even more likely to be vulnerable, and the stakes could not be higher. A single adversary could potentially
neutralize critical military and civilian assets. A signiﬁcantly higher level of cybersecurity protections are
required to secure the industry.
A new class of space infrastructure is required to address the growing needs of the space industry,
and the growing threat of cyber attack. Infrastructure as a Service has long been accepted in the computer
and telecommunications industries. While it may be infeasible for all space companies to adopt minimum
cybersecurity controls, a small number of Intrastructure Service Providers could readily do so. It is time for
the space industry to take the next logical step in maturation.

Big Risks in Small Satellites
The Need for Secure Infrastructure as a Service
Harrison Caudill (email@example.com) – April 29, 2019
The space industry is experiencing a wave of commoditization and expansion akin to the computer
industry’s transition from mainframes to compute clusters. The number of new satellites launched each year
continues to rise, with thousands of new satellites planned to be deployed over the next ﬁve years.
Typically, small satellites are used as part of a larger constellation, allowing any individual unit to fail without
compromising the integrity of the constellation as a whole. Improved resistance to single points of failure
combined with lower cost is driving several players to transition to constellations of smallsats.
The United States military relies heavily upon its space assets.[3, p3] Accordingly, Chinese and Russian
military doctrines include counterspace weapons and tactics speciﬁcally to deny that advantage to their
Western adversaries.[4, p20, 24] These nations are also actively developing their own space assets to
mirror those capabilities that the United States already possesses, as well as expanding beyond.[2, p4]
Outside of the military domain, the economic infrastructure of the United States relies heavily upon the
continued functioning of US-controlled space assets. America’s space infrastructure is a tempting target
for adversaries. While kintic-kill anti-satellite missiles (ASAT) do exist, they are still expensive and rare.
However, not only would it require hundreds of missiles to cripple a large constellation, it would also invite
immediate retribution (as ASAT systems are anything but stealthy), and create a serious debris problem
leading all closer to Kessler syndrome1, indiscriminately denying access to aggressor and target alike.
Cyberattacks represent a for more economical, straightforward and dangerously effective approach for bad
The fundamental weakness in satellite security is inherent: you can’t push a reset button. Nearly all
security models make the assumption that the owners have physical access to the asset – an assumption
which is hopelessly violated in space systems. While the advent of satellite servicing technologies presents
an opportunity to remedy this limitation, it could just as easily exacerbate the problem if an adversary were
to utilize that capability.[9, p13] In this environment, cybersecurity is paramount. Worse than losing an asset
on which one depends is losing an asset and an adversary gaining it. The United States depends not only
upon its own space assets, but also upon its adversaries either not possessing similar capabilities or at
least needing time and money to acquire them. North Korea, for example, could acquire synthetic aperture
RADAR capabilities by hacking an existing commercial constellation and Locking Out the owners.
Focusing strong new security regulations within Operations and Communications, opens the door for
commercial Infrastructure Service Providers to bear the burden of implementation. With or without security,
and whether using an external Service Provider or an in-house implementation, commands and data will
likely ﬂow through a Developer’s Operations and Communications systems. As those two Infrastructure
Services are reasonably consistent between organizations and missions, they represent excellent locations
for standardization and implementation of security controls.
Space operations are no longer the exclusive domain of powerful nation-states Criminal elements
have already shown proﬁciency with cyberattacks of satellites2[14, p31-33,37-39][6, §7p1]; nation states

are known to be far more sophisticated. With cyberattacks against space systems on the rise[6, §7p1], this
threat is very real and in need of immediate attention.
This paper proposes an economically viable solution to the lack of cybersecurity in the New Space
industry. Because convenience and affordability are critical to compliance, this solution includes the devel-
opment of Infrastructure Service Providers to offer secure and convenient alternatives to in-house design.
First, applicable threat vectors are discussed. Next, recommendations are made to address them. Finally,
a speciﬁc set of actions for the next six months are proposed.
Generally speaking, a constellation of satellites can be viewed as a compute cluster comprised of
multiple independent systems.[8, p10] Satellites are, for the most part, computers with peripherals and
network connections. The network connection doesn’t work the same way, the usage model differs, and the
stakes are higher, but the fundamentals are largely unchanged. The differences between space systems
and traditional compute clusters must inform any space cybersecurity solution.
Lockout, where an adversary permanently wrests control from the legitimate owner (Developer), is of
utmost concern. If an attacker Locks Out a systems administrator, they have until someone can physically
walk to the server and unplug it. That ultimate capability creates an incentive to be stealthy about success-
fully compromising a system. However, compromising a satellite and Locking Out the legitimate owner is
the ultimate transfer of ownership. Political and military pressure could, theoretically, be applied to entities
for hacking satellites – would the US really invade Iran if they were to hack a commercial weather-satellite
constellation and Lock Out the owners? It is believed that “. . . if a future conﬂict were to occur involving
Russia or China, either country would justify attacks against US and allied satellites as necessary.. . ”.[9,
p13] With a history of cyberattacks against US infrastructure[15, p5], and an immense ROI for success, the
problem of Lockout cannot be ignored.
The reliability of vendor-supplied components and the vulnerability of supply chains to backdoors are
both long-standing problems further exacerbated by the immaturity of New Space. While the introduction
of surveillance equipment or other sabotage within a supply chain is not a new tactic an additional risk
worthy of consideration is that of reliability. Traditional space missions, with large budgets, are at least able
to leverage a network of capable vendors; though even those vendors pay less attention to security than is
warranted.[8, p5] This category of risk is recognized as being a major issue and is at the heart of an
ongoing struggle with China regarding the 5G wireless rollout. While the defense industry may be taking
steps to mitigate the problem, commercial organizations are far less sensitive to security than they are to
proﬁt. Newer constellations of cubesats face an immature supply chain and often ﬁnd it more attractive
and more effective to vertically integrate.[5, p21] Few companies, whether they are satellite component
suppliers or operators, have the ﬁnancial incentives necessary to develop secure systems with appropriate
emphasis on supply-chain validation. As observed in the IoT industry, without external stimulus, the market
is likely to remain highly vulnerable to hardware backdoors and unreliable components.
Satellite communications systems are vulnerable to all of the same reliability and attack threats found
on point-to-point wireless links on Earth such as interference, weather, interception, spooﬁng, as well as a
host of standard networking security threats, and some threats unique to space operations. The wireless
link is frequently directly between a base station (analogous to a cell tower) and the satellite (analogous to
a cell phone). Alternatively, one can bounce the signal off of a relay satellite (analogous to a sat phone).
Satellites using the Direct method will frequently be out of contact with a ground station under the control
of the owner, and often ﬁnd themselves within sight of a ground station owned by an adversary. This effect
is similar to taking a long drive, and being exposed to a number of cell towers, and possibly some cell
tower emulators. Just like sat phones, satellites using the Relay Method may be able to launch with the
latest hardware on them, but will still be limited by the hardware on the relay satellite, which is typically
more expensive and longer lived; that means that any necessary hardware updates for a Relay system
will be rolled out more slowly than for a Direct system. Wireless systems typically require a great deal of
precision and care on Earth at the best of times; more attention, care, and protection is required for assets
With wireless communications as the only means of contacting a satellite, reliability is vitally important.
A satellite which cannot be contacted to execute a collision avoidance maneuver is just as dangerous
as a satellite that is maliciously placed on a collision trajectory. The dearth of commercial Carriers, and
prevalence of vertical integration makes reliability one of the largest risks in the industry. Many of the same
methodologies used to improve reliability will also improve the security of the wireless link. Resistance
to jamming, for example, works as well for unintentional jamming as for deliberate. With both China and
Russia investing heavily in electronic counterspace capabilities (including jamming and cyberwarfare)[6, p
20, 24], it is crucial to ensure the security and reliability of the communications channel.
Operations Systems, which ease the process of mission execution through simpliﬁcation and automa-
tion, are necessarily granted levels of access to critical systems which can be dangerous if not properly
protected. It is essential for Operations Systems to be empowered as they are tasked with managing
constellations currently in excess of one hundred (soon to exceed one thousand) satellites. To do so, an
Operations System may have access levels necessary to change encryption keys, reset passwords, or re-
install operating systems. With that level of access, the system must be guarded against unauthorized and
accidental command execution.
The space environment presents unique operational challenges leading to situations which consumer
hardware will never encounter. The JAXA Hitomi satellite was able to spin fast enough that it physically
broke apart. In 1998 the ROSAT satellite was pointed at the sun causing physical damage.[14, p31]
It was later revealed that the operational error was coincident to a cyber intrusion by Russia.[14, p31]
Whether by accident or intention, a command that fell outside of the safe operational limits of the satellite
was executed and physical damage resulted.
The operational system is typically also responsible for ferrying commands to a satellite, and receiving
data from them. In all cases, the commands must be sanitized to ensure proper protection of the asset
and of the environment. In cases where the data being collected is sensitive (such as imaging data for the
DoD), then the data pathways must also be secured. Without proper security in the operations systems and
software, attackers could potentially execute commands on the satellite and intercept resulting data.
It is recommended to utilize a combination of strong new security regulations3and market incen-
tives to efﬁciently secure space systems, encourage innovation, and ensure continued US market lead-
Given the critical nature of the systems to be protected, and the immense ROI of a successful attack,
strong new security regulations must be drafted and enforced. However, even with light regulations and
strict enforcement, there will still be issues of noncompliance without market-friendly infrastructure in place
to assist with the compliance burden. 4[21, p1,10][2, p24]
Enforceable minimum security standards and policies should be created and adopted, ensuring a
strong cybersecurity posture for the following categories of assets:
1. Space assets relied upon by the DoD: If the USAF depends upon a commercial weather data
provider to prepare for an operation, then that constellation represents a potential vulnerability. A
commercial imaging system used for military operations may carry data that is just as sensitive as a
2. Space industry assets which would be of great value to an adversary if hacked: North Korea
is reported to be expanding its space-based Earth observation capabilities.[4, p32] Their counter-
space aresenal also includes cyber methods. If they were to use their already sophisticated hacking
teams to wrest control of a commercial SAR (Synthetic Aperture RADAR) constellation, then US mili-
tary doctrine would be, at best, forced to transition to a contingency.
3. Critical civilian infrastructure: The United States’ civilian population and economy depend quite
heavily upon space infrastructure[2, p36], much as they depend upon utility companies. While the
US’ track-record with respect to protecting critical infrastructure from cyberattacks is checkered, it
is worth protecting newly-constructed critical systems.
4. Space assets capable of being a physical threat: As use cases continue to expand, it is worth con-
sidering the offensive capabilities of a given satellite.[2, p23] For example, a refueling station would
likely have propulsion on board and probably also have sufﬁcient reaction mass to reach the geosyn-
chronous belt. Even slow-moving satellites are travelling at 18,000mph; if they are maneuverable,
then they are as much a threat as any anti-satellite missile (ASAT).
3The author has speciﬁc policy and technical recommendations, but they are beyond the scope of this paper.
4Swarm Technologies, for example, was recently found to have deployed and operated satellites shortly after their application to do so
was denied, resulting in what some consider an insubstantial ﬁne, and a Consent Decree to come into compliance.
It is recommend that the United States use a combination of grants, loans, and contracts to encourage
two speciﬁc types of space-speciﬁc Infrastructure Service Providers be further developed and fully security
1. Mission Operations Services: The ability to execute missions in a clear, veriﬁed, and automated
manner is critical to stable and secure operations. When performing virtually any task, humans think
and act at a high level. In a similar manner, satellite operations are expressed in higher-level terms
such as “Have all satellits boost their orbit when able” vs “Have satellite 42 ﬁre its thruster for 3.6
seconds at next apogee”. Reliable mission execution and data management systems are of great
value to the market, independent of any security beneﬁts.
2. Communications Services: The communications system is one of the most critical and difﬁcult
systems to implement in a satellite. A regulated market operator will be far more capable of producing
a reliable, secure, and compliant system than a multitude of satellite Developers each attempting to
reinvent the wheel. Similar to terrestrial wireless Carriers, satellites could engage a wireless Carrier
who would hold the license, own and operate the infrastructure, and ensure reliability and security.
Market Adoption & Encouragement
The two proposed types of Infrastructure Service Providers (Operations & Communications) represent
a market-friendly mechanism for adoption of new security controls. Such a mechanism is critical for com-
pliance. Not only would these services provide a great step forward for cybersecurity posture, they would
also greatly improve the overall reliability and efﬁciency of America’s growing space infrastructure while
simultaneously lowering the cost and time barriers for development.
Solution: Specialization of Trade
Just as any specialized Infrastructure Service Provider (an ISP being an example) enables industry
growth, the proposed two Services:
•Will decrease the overall cost of compliance
•Will decrease the time necessary for implementation of a new space system
•Will greatly improve overall reliability and performance of new systems
•Have already been reviewed and tentatively accepted by regulators
By providing the necessary support to these two types of security-hardened Infrastructure Service
Providers (Operations & Communications), the US can adequately prepare for the inevitable (and ongoing[4,
p21][6, S7-1]) cyberattacks against its space infrastructure. A combination of regulatory and ﬁnancial assis-
tance (such as contracts, grants, and small business loans) can ensure the development of the necessary
market-friendly Service Providers.
Figure 1: In a typical deployment, all end consumers (price-sensitive commercial customers
and security-sensitive government customers alike) will work through the Developer’s infras-
tructure. The entire security burden then falls on the Developer. All commands and all data ﬂow
through their systems.
Mechanics of a Space Mission
As a space mission is an enormously complex endeavor, we will restrict ourselves to a relatively
straightforward example: that of a remote-sensing Earth-observation company. As shown in Figure 1, the
end consumers of the remote sensing data (perhaps a shopping mall tracking the fullness of its parking lots)
will contract with the Constellation Developer to image an area using one of its satellites. The Developer
will add that mission to their queue in their operations center, which will use their communications system
at the next available opportunity to assign the mission to an appropriate satellite. After being received by
the satellite’s radio, and relayed to its On-Board Computer (OBC), the observations will be executed at the
appropriate time. Upon completion, the satellite will use an upcoming contact opportunity to downlink the
data back to the customer via the Developer’s infrastructure.
Adoption of the proposed security controls in the two recommended Infrastructure Services (either
by internal implementation, or by contracting with a secure Service Provider) will lock down many of the
available attack avenues, and data pathways involved in the lifecycle of a space mission. As shown in Figure
2, it is possible for sensitive customers, such as the DoD, to use the capabilities of the Developer’s satellites
in a secure manner without the Developer being required to implement the necessary security controls,
and without the commands, data, and logs ever touching the Developer’s systems. Commands to the
spacecraft, and data returning from it are all passed through the secure Communications and Operations
A proper Operations System will be capable of simplifying mission execution, but will also protect
against unuathorized as well as accidental commands which may pose a danger. Once a satellite is
commissioned and establishes a regular operational cadence, the vast majority of its time is likely to be
Figure 2: If utilized, then the two secure Service Providers as well as the accompanying satel-
lite hardware (OBC and Radio) can lock down the critical data pathways. Security-sensitive
customers, such as the DoD, would be able to utilize a direct connection to the secure oper-
ations center. The burden of security no longer falls on the Constellation Developer alone, as
sensitive commands and data need not ever touch their infrastructure.
executing regular missions. In the example of the remote sensing system, that would mean observing tar-
geted areas and downlinking the resulting data. With such a standard mission in place, it is possible for
the Operations System to behave much like a ﬁrewall on a computer network by ﬁltering out and ﬂagging
bad missions. For example, the DoD would be able to mandate that the remote sensing system not be
used over the Pentagon, and have assurances that a responsible and security-hardened organization was
overseeing compliance. Recently, it was discovered that a constellation of US satellites was providing ca-
pabilities to China as a service, while the technologies necessary to do so appears to be unavailable for
export to China.5 Operational monitoring and security is essential for any sensitive mission or critical
Invariably, “Administrator” access will be required by the satellite Developer for actions such as software
upgrades, and protecting that administrative pathway is essential. During times when Administrator access
is required, there can be additional levels of security through the operations center for speciﬁc actions. For
example, one privileged mission might be the collecting of system logs, upgrading software, or resetting a
subsystem. Such actions will be necessary on a semi-regular basis, and must be supported in a reasonable
manner. The Operations System can require, for example, that such missions occur during business hours,
receive verbal approval from an operator at the company, or are executed with two-factor authentication.
Ideally, all satellite operations can be deﬁned as missions to be executed, and run through the secure
operations center, and that operations center will be ﬁltering, monitoring, and logging.
Ultimately, security-hardened Operations Infrastructure Services would be able to ensure sanity in the
tasks transmitted to the satellite, and integrity of the resulting data all while guarding against cyberattack.
5While it is not clear that operational ﬁltering as described here would have prevented this speciﬁc outcome, it is an excellent example
of authorized operations potentially going beyond acceptable legal and/or ethical limits.
Secure Operations Services can be developed using combination of such standard techniques as rules-
based access controls, multi-factor authentication, monitoring, and auditing. The Operations Service can
also provide secure data and command pathways for sensitive customers, and standardized/trusted logging
One such company, KubOS, already exists, and is fully committed to seeing these recommendations
become a reality. The economic model necessary to secure our space assets has already been demon-
strated, and needs only the appropriate ﬁnancial incentives necessary to evolve in a security-hardened
Because of the issues surrounding physical access to the satellite, as well as the fundamentally ex-
posed nature of the communications link, a secure communications system will be required. The commu-
nications system is the most likely location for Lockout to occur. Without that wireless link, the satellite is
completely and totally unavailable to the Developer. The communications system is also the most vulnerable
to Denial of Service through, for example, jamming.
There has been a great deal of recent effort regarding the easing of regulatory burdens. While
removal of unnecessary and unuseful regulatory barriers is appropriate, regulatory oversight and coordi-
nation exists for a reason. As more systems are deployed, and more players emerge, more and better
regulations are called for. The FCC and ITU, for example, do important and enlightened work, and will re-
main important stakeholders. Consider an extreme case: the Nuclear Regulatory Commission. Would
it be prudent to make it easy for your neighbor to build an experimental nuclear reactor in their back yard
after receiving a few million dollars in funding? A better way to consider this problem is to look at the Car-
rier Model. One does not need a license to use a cell phone as an end consumer. The Carrier Model for
satellites was pioneered with the FCC by BStar Communications6, and appears to have been subsequently
adopted (in rhetoric if not in fact) by other players in the market.
With the Communications and Operations Services more closely aligned with industry standards, the
differences between satellites and computer clusters may be minimized, permitting the application of stan-
dard and robust systems. The security industry already spends billions of dollars each year securing net-
works, compute clusters, and endpoints. If satellite constellations were normalized to behave more like
traditional systems, then standard utilities become available not just for security, but also for basic opera-
tions. Networking systems could use IPv6 permitting the application of standard networking security utilities,
for example. By normalizing the environment, one can leverage millions of man-hours of effort, and billions
of dollars worth of research and development.
6In January of 2018, the author and lead counsel (Henry Goldberg) met with leadership at the FCC’s Satellite Division (Jose Albu-
querque and Karl Kensinger) along with several other FCC stakeholders. During that meeting the full details of BStar’s Carrier Model
were discussed and no signiﬁcant problems were noted. BStar Communications was then invited to submit an application based on
the Carrier Model for operating the ﬁrst true wireless Carrier for space systems.
The economic barriers to a strong cybersecurity stance in the New Space industry can be all but
eliminated by supporting two types of security-hardened Infrastructure Service Providers (Operations &
Communications) and tailoring cybersecurity requirements to fall within their domains. An Operations Ser-
vice Provider is capable of ensuring that command and data handling for satellite systems are done in a
secure manner. Standard constellation management & operation would be available instantly to any new
Developer. Similarly, a secure Communications Service Provider could offer a reliable, efﬁcient, and secure
link to any new satellite. Collectively, these two Infrastructure Services are sufﬁcient to enact a critical set of
essential security controls to most any space mission. The economic and regulatory viability of these two
Service Providers has already been demonstrated. Because these two Services can be readily outsourced
to an external Service Provider, industry participants would have no need to hire the necessary experts,
and expend the necessary time and money to reap the beneﬁts they supply.
The Next 6 Months: Getting to a First Draft
It is crucial that action be taken to develop speciﬁc security policy recommendations. Several industry
participants and security experts already possess recommended policies at varying levels of complete-
ness. A small working group of such experts should be assembled and empowered. That working group
should include those with expertise in: space cybersecurity, physical security, space law, security policy,
and national defense.
The next six months should be dedicated to producing a ﬁrst draft of US Cybersecurity Policy recom-
mendations with an eye towards outlining the needs of space infrastructure.
First Summit: Outline
An initial summit should be held with the express goal of creating the outline for a ﬁrst draft of security
policies and standards for space systems. The ﬁrst step will be to grant the members an opportunity to
work together to form an outline and a framework. Upon completion of the ﬁrst summit, the working group
should be in possession of a framework and an outline with which to work semi-independently on assigned
Second Summit: First Draft
Once the members have completed their sections in coordination with industry, they should reassem-
ble for a second summit with the goal of compiling a ﬁrst draft of US Space Cybersecurity Policies. The
members will have been in contact while drafting their individual contributions, and will have been able to
work closely with industry at the same time. The net result of this process should be a set of policies that
have seen industry, expert, and legal review.
Cyber threats have kept pace with the explosive growth in space technologies. The US must protect
its current and future space assets. Typical security models assume physical access to the asset to be
protected, and fall short when applied to space systems. Afterall, what good is encryption if a foreign
adversary obtains the key, just once, and changes the locks? This nation depends upon its space assets
for both military operations and civilian life. The loss of those assets would be catastrophic, and doubly so
if they were lost to an adversary.
Space missions are notoriously complicated.Vendor networks for large satellites are established and
capable, though frequently lacking in security; smallsat companies frequently lack any option, secure or
otherwise. Few, if any, options exist for secure and auditable supply chains. Once a satellite has been
deployed in orbit, it is dependent upon a complicated web of systems just for basic interaction over its
wireless communications link. That link may be interfered with by accident or by deliberate jammming, it
may be hacked and spoofed, and at the end of the day, it is still the only option available. If the Developer
has passed those trials, they then must ﬁnd a way to operate the satellite in a sane manner while navigating
National Security issues, orbital collision avoidance, radio frequency collision avoidance, and prevention of
unauthorized access and control.
Cybersecurity policies and regulations will only help if companies comply with those requirements. As
it stands, any set of requirements that would be palatable to companies would be woefully inadequate, and
any set of requirements that are sufﬁcient would be economically infeasible for all companies to implement.
However, a third option exists in which sufﬁcient cybersecurity controls may be enacted while simultaneously
decreasing time and monetary costs to new companies. If new cybersecurity policies are written to fall
mostly within the Operations and Communications systems of a satellite constellation then it opens the door
for third party Infrastructure Service Providers to solve the problem. It may be infeasible for all companies
to enact sufﬁcient security controls, but a small number of focused professional Service Providers could
readily do so.
Focused professional Infrastructure Service Providers will be able to offer a more reliable and secure
option than most vertically-integrated companies can afford. They will guarantee that even the smallest
company with the biggest ideas, and the best innovation can still deploy their satellites, and make their
waves. The biggest difference is that they can do more with less time and less money while being more
reliable and more secure.
