Worst is yet to come, but they all warned you

CISA, FBI, Cyber Security specialists, they all warned you, I warned you, and I continue to do so.

Transnational criminal organizations, criminal hackers, are only getting better, and more organized. They have always been, but they are getting better and evolve faster.

This also means that YOU, and YOUR ORGANIZATIONS, must take this in consideration, and must adjust your posture according to this. Your risk register must be updated, and the likelihood of cyber events, at least should be raised or reviewed, especially on the ransomware side.

Doing so should put some level above the threshold you established, and some items that where falling under the « risk acceptance » option, will fall under the unacceptable, requiring compensation measures.

So you will update your security plan accordingly, while you adjust your risk posture.

A reminder on the risk management strategies :

  • Risk Avoidance – Change organization practices to avoid the risk
  • Risk Transference – Take an insurance, move the risk to a third party, BUT, keep in mind, there is no way you transfer 100% of the risk, which means, you need mitigation !
  • Risk Mitigation – Take action design to reduce the likelihood or impact of a risk
  • Risk Acceptance – After analysis, determining if cost makes the compensation irrelevant, then acceptance is the option
  • Risk Deterrence – Dissuade a threat to happen, which can only be applied to risks that can be affected by controlled factors

So you’ll place security controls, which are procedures and mechanisms that an organization puts in place to manage security risks.

You’ll follow the defence in depth approach, multiple controls for one objective, overlapping security controls.

These security controls fall under 3 categories :

  • Preventive, the goal being for the incident not to happen (you have a raid, so as when a disk dies, you don’t lose the data)
  • Detective, goal is to identify a failing preventive security control, or an incident
  • Corrective, restoring backups, because preventive controls failed, detective was missed, and you lost the data.

For each category above, you have many controls available (remember, people, process and technology somehow) :

  • Technical controls (technology based, like a firewall)
  • Operational controls (processes carried by humans)
  • Management controls ( conducting risk assessments, security planning, change management etc).

When your risk register is complete, you have the assessment done (exposure factor, single loss expectancy, you got your Annual Loss Expectancy by multiply SLE x ARO as in anual risk occurence), and you get a quantitative and qualitative assessment.

Your goals are defined via RTO (recovery time objective), RPO (recovery point objective), MTD (maximum tolerable downtime), and you know your MTTR (mean time to repair).

If you don’t know what adversary risks (aside of all the other existing risks) your organization face, have look to MITRE ATT&CK and check if anything is applicable to you, and therefore, if you have matching controls in place.

This week in the cyber news, helping you to have a real view of the threat landscape and what happens to others, so as you can actually review your posture, and adjust the above listed risk approach accordingly.
