Cybercrimes plague industries of all verticals and sizes, and there’s no end just yet. Small and medium-sized enterprises (SMEs) are particularly at risk because they have minimal resources to combat threats. Pervasively, across all sectors, there has been a clear call for cyber resilience to gain traction. Cyber resilience is the backbone that supports an organization’s overall cybersecurity strategy.
Businesses today are forced to operate in an ever-changing threat landscape, and traditional security protocols are unable to keep pace. To ensure their sustainability, they must redirect their attention to a more pragmatic strategy and turn to cyber resilience techniques.
Understanding Cyber Resilience
Cyber resilience is about how an organization responds to data breaches and cyberattacks while successfully carrying out business as usual. By using cyber resilience strategies, IT security teams can reduce expenses while quickly identifying and containing potential issues before they spread. Although proactive security is part of cyber resilience, it also considers measures created to reduce data risks after they have already affected the system. This covers strategies to ensure business continuity and built-in redundancy. Cyber resilience recognizes that there is no way to protect systems and data from attackers. Even with thorough defensive measures in place, data loss and downtime – whether caused by criminal activity, user error, hardware failure or natural disaster – can occur at any time. .
Percentage of attacks repelled and breaches averted can be used to gauge cybersecurity effectiveness, while recovery time (RTO), recovery point (RPO), and total system availability can be used to measure the success of cyber-resilience.
Take a systematic approach to cyber resilience
Now that we’ve established the definition, let’s look at some crucial best practices for improving cyber resilience using a tiered strategy.
1. Reinforce organizational gaps
Malware enters networks primarily through phishing scams. Employees are tricked into downloading malicious attachments, using fraudulent emails, text messages, pop-ups and web links. It is very important to train the workforce to be alert and consider any information they receive and act on it. Employees should be trained on phishing simulations, IT and security best practices, data protection and compliance needs. The vigorous implementation of such training programs will help reduce the risk and frequency of attacks and embed a cyber-resilience plan at the most exposed access points.
2. Sophisticated threats require sophisticated security
Cybercriminals are very resourceful and meticulous. They are changing their strategies to circumvent network firewalls and other protections as organizations become more adept at spotting potential dangers. Businesses now need to implement internet security with threat intelligence to recognize harmful attacks that might otherwise appear innocent. Advanced commercial antivirus software uses state-of-the-art technology to detect, stop, and remediate (contain the threat) malicious threats that other less capable antivirus software evades.
3.Use the 3-2-1 backup procedure for all organizational data.
Having data backups is crucial for business continuity as dealing with data loss is very complicated. The impacts of malware, such as ransomware, can be reduced by adopting a 3-2-1 backup strategy. In a 3-2-1 method, organizational data is duplicated at least three times globally, twice locally on separate media, and once offsite. This helps reduce data exposure in the event of an unforeseen event. Having both local backup and offsite backup provides businesses with additional alternatives for backup recovery.
4.Be sure to periodically perform a backup and security drill
Assessing disaster recovery methods and procedures is essential to ensure that business recovery goals are met through improved cyber resilience. And any recovery strategy is only good if it is tested regularly. To ensure that the business can be cyber-resilient when needed, regular testing criteria once a quarter or, at the very least, once a year should be performed. This will help assess both large-scale system recovery and simple file and folder recovery.
5.Engage an MSSP
Companies considering outsourcing their IT operations can use managed security service providers. Managed services companies proactively monitor company servers, reduce IT issues, and fix any issues that may arise. The majority of IT work is now outsourced thanks to advances in cloud computing. Without being present on site, the MSSP remotely accesses the networks and provides solutions to all IT challenges.
When employed, most MSSPs offer comprehensive solutions with extensive computing resources. Daily network monitoring, red team, incident response, cloud security posture management, infrastructure security, penetration testing, breach and attack simulation are all included.
Companies across a wide range of industries and geographies are investing in managed IT services and support partnerships to outsource their IT infrastructure needs, allowing their internal teams to focus on expanding their core businesses.
Businesses should be aware that no single cybersecurity solution can stop today’s sophisticated and ever-evolving cyberattacks. Despite heightened security, cybercriminals can still gain access to a company’s network and computer systems by taking advantage of human error or vulnerabilities. To build cyber resilience throughout the organization, it is crucial to embrace cyber resilience in this situation.
