Any operations online are susceptible to ransomware attacks, regardless of its size or stature. Even while it’s crucial to mitigate risk as much as possible, certain organizations will inevitably suffer
Enterprises must take specific actions to build resilience before developing a plan to defend them from ransomware attacks. Additionally, businesses need to be ready in the worst case scenario of attack.
Sequester any affected equipment
To contain the spread of ransomware after a breach, it’s crucial to isolate any compromised devices as much as possible. When ransomware is actually used, attackers are typically already well-established in the environment, so containing the damage becomes a race. This action should be included in a company’s ransomware incident response plan that has been practiced in the past.
Employ immutable backups
Although it functions similarly to other data backups, an immutable backup does not let data be altered or removed. The best defense against data corruption, whether intentional or unintentional, is this kind of backup. An immutable backup assures that businesses that are the target of a ransomware attack do not have to cough up the ransom to get their data back, and that hackers cannot encrypt data even if they gain access to the backup storage.
Organizations should perform numerous daily backups of their data, employ at least two copies, and keep one offline. If businesses become infected with ransomware, they should wipe off their old system and restore the most recent clean backup they have on file.
Even if firms can recover the data, remember that losing confidential client information to criminals is still a problem. Companies should take the time to build up additional safeguards than an immutable backup because hackers may sell or leak the information.
Establish and maintain a successful security program
To guarantee firms are aware of the locations, flow, and risk level of their most valuable data, they need to start with a system inventory. Businesses should continuously scan and examine electronic data, essential systems, physical media, services, and devices to identify any risks and vulnerabilities across their entire organization.
Companies should help their staff choose and execute the most recent environmental risk management controls. Additionally, businesses should routinely check that all of their system components are configured and working properly. To stay up with the growth of the current threat landscapes, organizations must constantly evaluate and determine the efficacy of their risk management strategy and procedures. Businesses should be sure to document lessons learned and make modifications as necessary.
Do not employ a hacker to decrypt files
In the blink of an eye, ransomware may spread throughout a network. Businesses must first isolate the infected device and remove it from the network if they hope to minimize harm and save their operations. This action will offer enterprises some breathing room while they decide how they want to respond to the onslaught. Under no circumstances should businesses pay a criminal to decrypt their stolen files.
