5 Ransomware Best Practices Every Firm Should Know
The resurgence of ransomware attacks in India has posed a great threat on various organization, compelling them to re-evaluate and renew their data protection strategies, believes Sandeep Bhambure, Vice President & Managing Director, Veeam India & SAARC.
According to him, the National Cybersecurity Month is an opportunity to educate businesses on the most effective ways of protecting against ransomware attack. With ransomware attack volumes increasing by 151% globally in the first six months of 2021, businesses of all sizes are aware of the threat. While ransomware attacks shot up globally, India was the worst hit nation with 213 weekly ransomware attacks per organisation.
“We believe the first-step towards building a resilient infrastructure is educating stakeholders and implementing accurate data back-up and protection solution/techniques. Further, devising an effective contingency strategy to mitigate the impact of the threats is equally important.”
Veeam has adopted the National Institute of Standards and Technology (NIST)’s best practice for businesses on how to protect data and guarantee business continuity, which is highlighted below:
Identify: Determine what environments exist which an attack might affect, what risks are associated with those environments, and how this all relates in context with your business goals.
- The human firewall – probing: Technology alone cannot protect your organisation. Everyone must be aware of security risks and understand how to report potential incidents. Evaluate the cybersecurity awareness of your workforce and test them regularly through phishing simulations.
- Plan for business continuity: Outline the processes that are crucial for your organisation’s business continuity such as essential contacts and actions should a disruptive event occur. This plan should be stored in a separate location, so that it is immutable and available 24/7/365.
- Tag your digital assets: Identify and tag the assets that are most critical to your organisation so that you can identify and protect them effectively.
Protect: Develop and implement appropriate safeguards to ensure critical infrastructure service delivery by proactively supporting your ability to limit or contain the impact of a cyber-attack.
- Educate your human firewall: Training your staff around cybersecurity is a highly effective way to raise your protection level. This education must take place continuously, with employees receiving updates and new briefings as threats arise whatever their job titles.
- Invest in your digital hygiene: Make sure you’re doing everything in your power to make life harder for malicious actors to ‘infect’ your organisation. This includes creating unique passwords that are updated regularly, using multi-factor authentication, and removing unused devices and applications.
- The 3-2-1-1-0 rule: Keep at least three copies of each piece of important data you have. Store your backup data on two different media types and replicate one copy off-site. Further protection can be achieved through encryption and only using infrastructure that is secure by design.
Detect: The detect function allows for a timely discovery of cybersecurity events and is a critical step to setting up a robust cyber strategy. The faster an event is detected, the faster its repercussions can be mitigated.
- Set up detection systems: The biggest risk is that they may rapidly propagate other systems, so gaining visibility into potential ransomware activity is key. Set up timely alerts when defending against viruses, malware and ransomware.
- Place virtual tripwires: When any suspicious activity is observed virtual tripwires like an unused admin account with alarms tied to it will trigger a red alert instantly.
Respond: The respond function helps users develop techniques to contain the impact of cybersecurity events by ensuring you develop and implementing appropriate actions.
- Create an incident response plan: Outline procedures for detecting, communicating, controlling and remediating security incidents so that employees know how to best respond to cybersecurity events when they arise.
- Be calm and accountable: Never blame IT teams or employees for a breach. It won’t help you respond to the incident and will generate even higher levels of fear and stress. Stay calm and get the right people together to activate the incident response plan as quickly as possible.
Recover: Not all cyber-attacks can be averted, so make sure you have a recovery strategy in place for those moments when your cybersecurity defences have been breached.
- Define your recovery strategy: Prioritise action points that can be used to undertake recovery. Back up your data and make sure backups cannot be accessed by an attacker.
- Design your recovery: Backup systems must be designed with recovery performance in mind, rather than simply focusing on the amount of time the backup will take. Determine what your recovery SLAs are in terms of the RPO and RTO values that are acceptable to you.
“The war against ransomware is real and everyone must be prepared for an attack on their data,” said Rick Vanover, Senior Director, Product Strategy at Veeam.“The good news is that by preparing in advance, you can align to a framework that provides a reliable strategy when operations are disrupted. As well as having a plan, cybersecurity is about creating a culture where all employees are aware of their role in protecting critical data and systems by exercising impeccable digital hygiene.”
