IDENTIFY, PROTECT, DETECT, RESPOND, RECOVER

The Ministry of Justice (MoJ) is required to adhere (but prefers to exceed) to the Minimum Cyber Security Standard (MCSS).

The Standard

The UK HMG Security Policy Framework mandates protective security outcomes that the MoJ must achieve (and suppliers to MoJ, where they process MoJ data/information).

More information is available from https://www.gov.uk/government/publications/the-minimum-cyber-security-standard.

IDENTIFY

IDENTIFY is a prerequisite standard that requires:

  • appropriate information security governance processes;

  • identification and cataloguing of information held/processed; and

  • identification and cataloguing of key operational services provided.

PROTECT

PROTECT is the core standard to provide fundamentally defences to information and requires:

  • access to systems and information to be limited to identified, authenticated and authorised systems/users;

  • systems to be proportionally protected against exploitation of known vulnerabilities; and

  • highly privileged accounts (such as administrative level) to be protected from common attacks.

DETECT

DETECT is the core standard to detect when attacks are taking, or have taken, place and requires:

  • capture event information (and apply common threat intelligence sources, such as CiSP);

  • based on PROTECT, define and direct monitoring tactics to detect when defence measures seem to have failed;

  • detection of common attack techniques (such as commonly known applications or tooling); and

  • implementation of transaction monitoring solutions where systems could be vulnerable to fraud attempts.

RESPOND

RESPOND is the core standard to define the minimum of how organisations should respond to attacks and requires:

  • development and maintenance of an incident response & management plan (including reporting, roles and responsibilities);

  • development and maintenance of communication plans, particularly to relevant supervisory bodies, law enforcement and responsible organisations such as the NCSC;

  • regular testing of the incident response & management plan;

  • assessment and implementation of mitigating measures on discovery of an incident (successful attack); and

  • post-incident reviews to ensure feedback into the iteration of the incident response & management plan.

RECOVER

RECOVER is the core standard to define the minimum of how organisations should recover from an attack once it has been considered closed, and requires:

  • identification and testing of contingency mechanisms to ensure the continuance of critical service delivery;

  • timely restoration of the service to normal operation (a plan to do so, and testing of that plan);

  • from DETECT & RESPOND, immediately implementing controls to ensure the same issue cannot arise in the same way again, ensuring systematic vulnerabilities are proportional remediated.
