Penetration testing, commonly known as pen testing, is a simulated cyber attack against your computer system to check for exploitable vulnerabilities. It involves certified ethical hackers who mimic the strategies and actions of malicious attackers to identify and rectify security weaknesses before they can be exploited. Pen testing is critical to a comprehensive cyber security strategy, providing invaluable insights into your security measures’ effectiveness and helping safeguard sensitive data and maintain business continuity.
Pen testing is necessary because it helps organisations:
- Identify Security Gaps: By uncovering vulnerabilities before malicious actors do, organisations can address these weaknesses proactively.
- Evaluate Security Controls: It validates the effectiveness of existing security controls and policies.
- Comply with Regulations: Many industries and compliance schemes require regular pen testing.
- Improve Incident Response: It helps streamline the organisation’s response to actual security incidents.
Best Practices for Penetration Testing
To maximise the effectiveness of penetration testing, organisations should adhere to the following best practices:
1. Comprehensive Scope Definition
- Why It’s Important: Penetration tests are pointless without a well-defined scope. The right scope covers all critical areas of an organisation’s security, giving you a clear picture of the state of your defences.
- How to Do It: Businesses must work with their cyber security service provider to clearly outline the systems, networks, and applications to be tested and include all high-value assets and critical infrastructure components.
2. Realistic Simulation
- Why It’s Important: Penetration testing must simulate real-world attack scenarios to allow businesses to identify how well their security controls can withstand genuine threats.
- How to Do It: Ethical hacking should involve tactics, techniques, and procedures (TTPs) commonly used by malicious actors. At OmniCyber Security our world-class team are constantly updating their practices to stay in line with the latest trends in hacking.
3. Engaging Experienced Professionals
- Why It’s Important: Engage the services of experienced and certified penetration testing professionals to ensure that testing has the highest standards of expertise and ethical considerations.
- How to Do It: Look for a security service provider with a proven track record in delivering reliable and effective penetration testing services. CREST Accreditation is the mark of penetration testing excellence and identifies a provider as someone you can trust to treat your systems with respect and confidentiality.
4. Collaboration with Internal Teams
- Why It’s Important: Successful penetration testing requires open collaboration between external cyber security experts and internal IT teams, and both sides need to clearly understand the objectives and processes of the pen test to get the best results.
- How to Do It: Foster open communication and cooperation between your internal teams and the penetration testers. It can also be useful to limit the knowledge of the pen test to a few senior members of staff, to get the most realistic response to the simulated attack from the team.
5. Prompt Remediation
- Why It’s Important: There’s no point to doing a penetration test if the uncovered vulnerabilities aren’t fixed. A structured and swift process of addressing and patching vulnerabilities should follow a pen test.
- How to Do It: Develop a prioritised remediation plan based on the severity and potential impact of identified vulnerabilities, as described in the engagement report from OmniCyber Security. Assign responsibilities and set deadlines to ensure that vulnerabilities are addressed promptly.
6. Regular Testing
- Why It’s Important: After remediation, it’s time to start thinking about the next test. Cyber security is not static, and threats are always changing. Arranging regular tests ensures that an organisation’s security measures remain effective against evolving threats and maintain compliance with key schemes.
- How to Do It: Integrate penetration testing into your regular security maintenance schedule. Annual or bi-annual testing is recommended for most organisations, but high-risk environments may need more frequent assessments.
Adhering to these best practices in penetration testing helps organisations fortify their defences against cyber threats. With a comprehensive scope, realistic attack scenarios, experienced professionals, and regular cadence, businesses can significantly boost their security.
