What does TISSM mean in UNCLASSIFIED

Theory of Information System Security Menace (TISSM) is a framework that focuses on identifying, analyzing and managing the security risks associated with the development and use of information systems. It outlines strategies to protect against potential attack vectors and vulnerabilities while providing secure networks.

TISSM helps organizations by providing an organized approach to understanding their security needs, developing security policies, mitigating vulnerabilities, and improving their overall security posture. This includes assessing user access requirements, using security technologies such as encryption, performing regular vulnerability scans and penetration tests, and monitoring user activities.

The core principles of TISSM include risk assessment, prevention through hardening of assets, detection to identify threats when they occur, response to mitigate threats before they can cause harm, recovery which restores affected services or assets quickly after an incident, and education which keeps users informed on best practices so they can make secure decisions.

The components of TISSM are risk assessment for identifying assets that should be protected; prevention through hardening assets that contain sensitive data; detection by monitoring user activities in real-time; response through making quick assessments about threats detected and acting accordingly; recovery for restoring assets that have been damaged or compromised; and education for keeping users informed regarding best practices in secure computing.

Organizations need to first assess the risks posed by their information systems in order to identify potential sources of vulnerabilities. Then they should use appropriate security technologies such as encryption or tokenization to protect data at rest or in transit. Deploy active monitoring solutions to detect suspicious activity and respond immediately if a threat is detected. Finally they should ensure a robust recovery process is established in case any assets become compromised or damaged due to an attack.

A number of documents are needed when creating a successfulT ISSM plan including an asset inventory list which identifies all systems used within the organization; a network diagram showing how those assets interact with each other; a vulnerability assessment report which highlights any gaps in security measures; a policy document that defines user rights/responsibilities relating to system access/usage; an alerting policy outlining what type of alerts will be sent out based on system events occurring; and an incident response plan detailing how incidents will be handled from start to finish.

When hardening systems it’s important firstly to disable all unnecessary services or applications running on it - removing what you don’t need reduces your surface area for attack. Secondly keep software up-to-date with critical patches applied promptly - old software can easily contain exploitable vulnerabilities. Lastly use endpoint protection solutions such as antivirus/anti-malware software - these provide another layer of defense against malicious actors trying to gain access.

Regular vulnerability scans provide invaluable insight into weaknesses within systems so organizations can prioritize areas where additional protections should be put in place quickly before attackers discover them and exploit them for their own benefit. They also allow organizations track patching progress over time so they can measure just how effective their mitigation efforts have been.
