How To Deal With a Cyberattack

With a growing proportion of the global economy and communication moving online, more and more companies are at risk of falling prey to a wide range of cyberattacks. Digital threats like malware, social engineering schemes and phishing scams are responsible for an ever-increasing cybercrime rate.
This makes it crucial for companies of all sizes to have a business disaster recovery plan in place to mitigate and alleviate any losses if such an event occurs. 
Recovering from a cyber security incident can be challenging, especially if you have lost information that was critical to your business operations. The good news is that you can limit the amount of damage to your company by developing a robust IT recovery plan in advance and by testing its effectiveness. 
However, if your business has already fallen victim of a data breach and you need to know what to do after a cyberattack, Redpalm have compiled a list of steps to assist you in minimising and containing the damage.
Let’s take a look at how this can be done.

• Limit and Control the Extent of the Data Breach

After an attack, the first thing you should do is work out which servers and IT equipment have been compromised. Once you have that information, contain the spread of the breach as swiftly as you can by securing endpoints, devices and servers that aren’t affected by the attack. 
Below, is our list of things you can do to immediately try to contain and limit the spread of the breach:

• Disconnect your internet connection
• Restrict remote access
• Fortify your firewall settings
• Install any pending security updates or patches
• Change your passwords across your business network

Once you’re certain you’ve been compromised, isolate any known compromised devices by taking them off your network. However, if you want any forensics performed on them to identify the source of the attack, DO NOT shut them down as most forensic data is lost on system shut down.
Ensure that you create strong new passwords for every affected account immediately. It’s also important that you avoid reusing old passwords or the same password across multiple accounts. This way, if a cyberattack were to happen again in the future, the damage will be restricted to one system or account. 
It is understandable that after a data breach occurs, you’d want to delete all your old records and data. However, we highly recommend preserving the evidence to find out how the breach occurred and understand the weaknesses in your infrastructure.

• Manage the Fallout by Notifying Employees and Managers

Inform your staff about the cyberattack and define clear authorisations for all team members moving forwards. Ensure that both internal and external business communications are monitored and properly encrypted. 
It is crucial for your business that all the employees and teams remain on the same page as your company recovers from the attack. Depending on the extent of the damage, you may wish to seek legal advice to ascertain if, when and how to inform your customers about the data breach. 
If you have been the victim of a data breach, you need to report it to the ICO within 72 hours of discovery. To find out more about reporting to the ICO, click here.
Moving forwards, we’d suggest implementing routine security checks and evaluating your response to future test cybersecurity incidents, to minimise the likelihood of a similar attack taking place in the future. 
Identify the lessons you have learnt and make adjustments to your security response plan to remain prepared. 

• Analyse and Evaluate the Breach

If your business is a victim of a wider-reaching cyberattack that has infected several other businesses, ensure that you closely follow any developments and updates on the situation. This way you’ll be kept aware of any additional help that is made available. 
Irrespective of whether you are a part of an extensive network breach or a solitary victim, you will need to assess and evaluate the root cause of the cyberattack. You need to find out its basis and point of origin within your business network so that you can safeguard yourself against a similar attack, should it happen again. 
Ask yourself these questions to thoroughly gauge the extent of the breach:

• Which employees had access to the compromised servers?
• Which network connections were being used when the data breach occurred?
• How was the breach initiated?

Check your security data logs on your antivirus program, email providers or Intrusion Detection System to find out the exact moment the attack was initiated. If you are finding it difficult to pinpoint the origin and scope of the breach, the experts at Redpalm can provide assistance. 
We have a team of qualified cybersecurity professionals who will not only help you recover from the breach but also protect your IT environment from being compromised in the future.

• Evaluate, Improve and Implement Security Measures

After a cyberattack, it is incredibly important that you update your IT disaster recovery plan, along with your business processes and techniques. This should be tested routinely and rigorously to ensure security and stability. At Redpalm, we conduct these tests in a simulated environment for our cyber security partners to stress test your security processes and ensure your business network is kept as secure as possible from digital threats.
