Avoid Shared Hosts

Info Tip: Kicksecure should preferably be used only on computers without shared access.

It is unwise to allow others to use your computer, even if they are trustworthy individuals. If they are not equally knowledgeable in computer security, then one mistake could potentially lead to compromise of the entire system. [1]

Needless to say, Kicksecure should not be hosted in the cloudarchive.org iconarchive.today icon, on a foreign server that is not controlled by the user, on a virtual private server (VPS)archive.org iconarchive.today icon, or other remote hosting options. The risks include: [2] [3]

  • Data on these systems is readily accessible to their owners.
  • Data can be accidentally or deliberately altered / deleted.
  • Legal ownership of data is disputed.
  • Shared technological vulnerabilities include insecure interfaces and application program interfaces (APIs), data loss / leakage and hardware failure.
  • Proven vulnerability to large scale attacks like "hyperjacking"archive.org iconarchive.today icon, along with exposure to traditional threats like network eavesdropping, invasion, denial of service attacks, side-channel attacks and so on.

Use a Dedicated Host Operating System and Computer

Both Kicksecure and [[Kicksecure-Qubes|Template:Q project name]] users should avoid dual / multi-boot configurationsarchive.org iconarchive.today icon. The other OS (like Windows) could modify the unprotected /boot partition or firmware to maliciously compromise Qubes or the host OS, and also potentially spy on user activities.

[[Kicksecure|Template:Non q project name]] users are recommended to use one dedicated host OS just for hosting Kicksecure VMs. Otherwise, if the host OS which is used daily is compromised, Kicksecure cannot provide any additional protection. This is because the host is part of the system's trusted computing base (TCB)archive.org iconarchive.today icon:

For a computer system, the trusted computing base or TCB comprises the set of all hardware, software, and firmware components that are critical to establishing and maintaining its security. Typically, the TCB consists of an operating system with all its in-built security controls, individual system hardware, network hardware and software, defined security procedures and protocols, and the actual physical location of the system itself.

...

Maintaining the confidentiality and integrity of data on a system is a prime responsibility of the TCB. The trusted computing base is also charged with enforcing the system’s security policy, and is the only component of a system that operates at such a high level of trust. This means that if any part of the TCB is subverted or contains flaws, the overall security policy of a system may be compromised.

See Malware and Firmware Trojans to learn more about the impacts of a compromised TCB.

For even greater security, the dedicated host OS can be used on a computer solely bought for Kicksecure activities. Ideally this computer will have never been used for anything else before, negating the risk of a prior hardware compromise.

Footnotes

  1. If necessary, this risk is partially mitigated by creating untrusted domains in [[Kicksecure-Qubes|Template:Q project name]] for other users.
