What is Cyber Resilience
Cyber resilience is a measure of an organisation’s ability to manage a cyber attack or data leak whilst continuing to operate as usual. Organisation’s must have the ability to recover quickly from cyber attacks, such as a ransomware assault, and resume normal operations.
According to Mimecast’s The State of Email Security Report 2020 organisations are still seeing data loss (31%), a negative impact to employee productivity (31%), and business downtime (29%) due to a lack of cyber resilience.
The goal of cyber resilience is to actively safeguard your entire organisation, taking into account all of your infrastructure’s insecure components.
If you’re fully prepared you’ll be able to secure your operations, decrease your exposure to cyber threats, and mitigate the impact of attacks.
Why Cyber Resilience Matters
When employees are unable to access data stored on the network or on company issued devices, the effect is more than just lost productivity. Downtime and system outages can have an impact on how you connect with customers and partners. It could result in you losing out to a significant competitor during a crucial stage of talks, as well as a tarnished reputation and diminished credibility. When downtime occurs frequently, it depletes IT resources and diverts IT personnel away from other critical strategic objectives.
As a result, while calculating the true cost of downtime, you must consider more than just the hourly cost of affected customers; the consequences could be vast:
Measures to Strengthen Cyber Resilience
It’s a good idea to have processes and tools in place to achieve cyber resilience and to continually check and verify:
Start by recording your assets and the security measures you need to implement to ensure they are secured.
Phishing assaults are still the most common way for malware to spread. Employees are tricked into downloading dangerous code using deceptive emails, attachments, and web links. Ensure employees are fully trained & vigilant.
A sophisticated corporate antivirus solution employs cutting-edge technology to identify, prevent, and remediate dangerous threats.
Relying on users will eventually result in data loss. Backups on a regular basis can be the difference between paying tens of thousands of pounds in ransom and recovering your data without the need to do so.
Cloud computing is hugely beneficial to businesses as it improves efficiency, reduces operational headaches and decreases costs, however it’s important ensure that data flow to/from the cloud is secured.
Remote access to files has proven to be critical for business continuity with so many employees now working from home. Ensure users can access files remotely & securely.
Have consistent detailed visibility across all of your environments so that you are aware of vulnerabilities and threats to your business.
Consider using a managed service, especially if you don’t have the resources available internally, they can provide peace of mind and ensure quick responses.
Improve your protection against cyber attacks by checking continuously for vulnerabilities and prioritising remediation.
Attacks on critical systems are on the rise and emerging threats make it difficult to keep up-to-date with patching. You need to ensure that patches are applied as soon as is reasonably possible.
Red teams run targeted testing to assist with risk discovery, compliance checks and to verify any results.
Ensure you are constantly vigilant by obtaining frequent vulnerability reports giving you actionable insights and analytics.
How to Achieve Cyber Resilience with Automated Security Testing
Continuous automated testing is an invaluable solution for securely testing your systems, networks and applications by emulating cyber attacks. In a matter of hours you can identify where you are most vulnerable, prioritise remediation and assess how your security has improved, or not, over time.
You can continuously assess and reduce your cyber security risk by frequently testing and acting upon the results.
Automated security testing can significantly improve your cyber resilience on a continuous basis by carrying out the following:
Identifies gaps in security and potential exploitation.
Active exploitation & post exploitation of your network.
Gives complete visibility of the kill chain, clarifying what needs to be fixed & the immediate impact of the fix on breaking the kill chain.
Assign & prioritise suggested remediation to members of your team.
Overview of your overall security posture assessment and top hacking achievements, plus the most cost-effective remediation actions to be taken.
Test in development & UAT environments, plus regular ongoing testing.
Scans your external network infrastructure & detects critical web application flaws.
Including all of the OWASP Top Ten
How to Achieve Cyber Resilience with Manual Security Testing
Whether implemented internally or establishing a strategic partnership with a 24×7 managed cyber security service, manual testing helps to achieve your security objectives and compliance obligations, critical to running your business and protecting your customers.
Manual testing can significantly reduce the risk of an attack and ensure you can recover quickly from any breaches by carrying out the following:
Active threat hunting identifies potential areas of compromise. Works as an extension to your security team, providing faster incident response times.
Red team testing discovers vulnerabilities, checks compliance and verifies findings.
Monitor emails/telephones for attempts to gain credentials or access.
Firewall / Endpoint / O35 (& more). Monitoring & management with 24×7 access to skilled security experts as an extension of your security team. Full incident analysis, remediation, change control & system updates/upgrades.
Full unified patching across your organisation securing all endpoints and infrastructure.
Real-time analysis of security events generated across your entire infrastructure.
Defend against advanced and complex security threats with a 24×7 cyber security centre that monitors, alerts and remediates, giving complete visibility and control.
Combined Automated & Manual Security Testing
Combining automated and manual testing with internal business processes helps you to continuously validate your overall security posture whenever you wish to (daily, weekly, monthly), with minimal in-house resource (i.e. one person for a few hours), and without needing to be experts in all areas of cyber security.
Combined with the support of a dedicated managed service that’s focused on monitoring and managing your critical assets around the clock, you get the best of both worlds, whilst also being in a position where instantaneous reporting as a result of automation empowers you with the intelligence needed to hold the service, and other vendors to account.
As the effects of a data breach can be technical, social, and financial, every business must prioritise cyber resilience by integrating business processes with IT. The data and technologies that drive our digital economy are critical to business success.
Being cyber resilient now will help to avoid disaster in the future.
