Recovering from a security breach requires a multi-layered approach. Key strategies include conducting a post-breach audit to identify vulnerabilities, enhancing network monitoring for real-time threat detection, and regularly training employees to prevent human errors like phishing attacks. Implementing a zero-trust security model ensures that no one is trusted by default, while multi-factor authentication adds extra protection. Regular security audits are particularly effective for ongoing defense, but over-reliance on antivirus software is insufficient. A real-world example is Twitter's 2020 breach, which led to improved access controls and employee training.

1- Ensure that business continuity plan is in place, reviewed, updated and tested on regular basis to determine what are the plan of actions in case of security incidents are discovered. 2- Conduct a security awareness program to all stakeholders 3- Implement Information Security Policy. 4- Conduct an internal and external vulnerability security assessment on regular basis to discover and then close any vulnerabilities before exploit it.

It's impossible to completely prevent a security breach; however, you can reduce the chances by training personnel beyond a "check the box" training as well as remaining current with security controls through an assessment and continuous learning. Additionally, the best investments with a high return are: (1) ensuring personnel know how to respond appropriately to mitigate the impact of a security breach; and (2) using technical measures such as encryption. Notable, using today's encryption that rely on algorithms using prime factorization are susceptible and any encryption should use those leveraging NIST's newly introduced lattice-based cryptographic standards. In terms of enrypted data, most notification laws exempt encrypted data.

Fixing the hole is obvious and needed. however, go a little deeper, the next break will be somewhere else using a different vector. ask yourself: Did the monitoring and alerting give sufficient notice? Are the tools you have properly implemented? Are you people ready, is their confidence to respond appropriate? Do you know your weak points? we all have weak points, knowing them is essential to manage them.

When a security incident occurs, it's critical to not only resolve it quickly, but also understand how to prevent it from happening again. Preventing future incidents requires in-depth analysis, improvements in safety processes and ongoing staff education. Collect all the data you can about the accident to understand exactly what happened. Analyze logs, recordings and traces left by attackers. To prevent a security incident from happening again, you need to take a holistic approach involving advanced technologies, improved processes and ongoing staff training. Implementing proactive controls and periodically reviewing security practices are critical to keeping your organization safe from future attacks.

You must immediately take action to avoid any escalation of the same or other incremental security incidents by implementing more detection methods. Add to this by implementing more security intrusion prevention methods. If you are not using a security framework such as NIST them you will want to consider whether you should not adopt one quickly. By implementing a security framework you will be able to develop your company’s anomaly detection processes and procedures, which you will then be assessing when you experience security incidents or near incidents in future. Follow the mantra “implement once, use many times.” to continually evolve your security hardening.
