Java and other languages which compile to Java byte code and run in the Java virtual machine can have their access to other applications controlled at the virtual machine level. There is growing concern that cyberspace will become the next theater of warfare. As Mark Clayton from The Christian Science Monitor wrote in a 2015 article titled "The New Cyber Arms Race": The principle of “least-privilege access” should be followed throughout your entire IT environment. This means granting database, network, and administrative account access to as few people as possible, and only those who absolutely need it to get their jobs done. Containment, eradication and recovery: Isolating affected systems to prevent escalation and limit impact, pinpointing the genesis of the incident, removing malware, affected systems and bad actors from the environment and restoring systems and data when a threat no longer remains

An access-control list (ACL), with respect to a computer file system, is a list of permissions associated with an object. An ACL specifies which users or system processes are granted access to objects, as well as what operations are allowed on given objects. Chris Clearfield.

Firewalls serve as a gatekeeper system between networks, allowing only traffic that matches defined rules. They often include detailed logging, and may include intrusion detection and intrusion prevention features. They are near-universal between company local area networks and the Internet, but can also be used internally to impose traffic rules between networks if network segmentation is configured.

Retrieved 15 June 2017.For a computer to be 100% secure, it must be disconnected from everything ( air-gapped) and physically isolated to prevent anything getting installed. For example, you'd need to turn off all drives that allow software to be installed (e.g., a disc drive) and turn off ports (e.g., USB (universal serial bus)) that allow drives to connect to the computer. Cryptographic techniques can be used to defend data in transit between systems, reducing the probability that the data exchange between systems can be intercepted or modified.
