Cybersecurity issues are a concern for all of us, not just IT specialists. If a malicious email manages to make its way inside a company's network or a person’s device goes haywire, then it is the person in front of the keyboard who will be the first line of defence. Quick and effective cyber incident response from a non-technical user can really make a difference between a small problem and a major leak of confidential information.
Most people get scared when their computer starts doing things it normally wouldn’t. They might simply shut the laptop without logging out or just throw themselves at the warning windows. But such hesitation only gives a virus more time to infect the entire company's network. When employees know what to do step by step, they are more likely to act without hesitating.
This guide is meant to do just that. By familiarising yourself with the principles of online security, you will learn what a threat looks like, how to contain it safely, and whom to inform about it. You do not have to be a coder to guard your digital workplace effectively.
You cannot react to a digital threat without even knowing what you are looking for. Cybercriminals have different ways of stealing data or shutting down operations.
You rarely get a new virus installed without you noticing even after it is too late. You may realize your PC is unusually slow, multiple pop-ups could start appearing or the system might freeze. Also, there is nothing wrong in actually logging out from applications with which you normally deal in case you forget backing up the session or that they have been hijacked as well. In the same vein, if others report receiving strange messages sent from your account, then the red light should turn on big time.
It cannot be stressed enough how important the first 60 minutes after you decide that you are under attack are. This is when everything counts the most.
Think of yourself as a fireman and your goal is to contain the fire from spreading as far as possible. You are not recommended to power down a computer. Do it only if that is what the security staff tells you, however, leave everything else as it is at the instance of your shock. Besides, one of the very preventive measures to be taken is removing the sole infected computer from the network by unplugging the Ethernet cable and disabling the Wi-Fi. With this move, you literally prevent the malware from going any further than just one device.
Do not forget to do a bit of detective work and gather clues about the incident to make the work of the experts easier. Make a note of the task you were performing at the moment of the attack, the exact time, and of any error codes or messages that appeared. You can take snap shots of your screen with the help of your mobile if that comes handy.
Get hold of your IT team or the security personnel right away. You should never send an email using the compromised device. Instead, use a different computer or a smartphone to call them. Mapping out a communication chain in advance only makes it easier when you need to know who to contact in a situation like this.
Having a clear and concise incident response plan template is absolutely essential if you want to handle a security breach without going into a frenzy. When a breakdown of clarity is inevitable, that is when a plan comes in handy by making anyone able to perform proficiently even under the hardest stress.
According to VPNOverview experts proficiency is not just a matter of skills but also of readiness and learning support. It is the central idea that everybody on the team should be fully aware of their roles in the chain.
Possessing the knowledge of digital privacy and security is going to be like having a secret weapon at your disposal, so why not get along with the story provided by VPNOverview? More importantly, make an important role transition from a passive to an active defender in your network.
Having a personal cyber attack response plan gives you a clear path forward. Here is a breakdown of the critical phases.
|
Phase |
Action Required |
Goal |
|
1. Identify |
Recognize unusual system behavior or suspicious emails. |
Catch the threat early. |
|
2. Contain |
Disconnect from the internet and local network. |
Stop the spread to other devices. |
|
3. Eradicate |
Wait for IT to scan and remove malicious files. |
Eliminate the root cause. |
|
4. Recover |
Restore data from secure backups. |
Return to normal operations safely. |
|
5. Post-Attack |
Review what happened and update security practices. |
Prevent future incidents. |
Go with your feelings if something fishy is going on with that link, tell to let it be known. The good thing about early detection is that it will come in handy when you are finally ready to respond to any kind of threat.
Again, isolation is an important step. Pulling the digital plug saves the rest of an organization from being affected by infection.
IT support is the one who actually gives the go-ahead for the usage of any software tools that might be necessary for the purpose of scanning to detect and eventually cleaning and removal of any traces of malware from the system. In other words, system files should not be executed or manipulated explicitly by the user.
Cleaning out the machine is the first thing that the technicians will do before engaging with you in testing different methods to which may include restoring your files from the backup that has been marked clean and is fully functional. Only after this point will you be allowed to reconnect to the network.
After everything has calmed down, be ready to do a post mortem. Human errors frequently play a significant role in the security breaches that we experience, so familiarizing yourself with steps to prevent incidents occurring when you least expect is part of the ongoing learning process.
Good communication prevents rumors and ensures a coordinated cyber attack response.
Tell your immediate workgroup if a breakdown in operations due to your computer being out of service status is expected to affect ongoing projects. However, be guided by firm rules as to whether or not to share details of the breach with other departments. Worry can, after all, be just as contagious as viruses.
Non-technical users should never communicate with external stakeholders about a breach unless explicitly instructed. Legal and PR teams must handle notifications to customers, partners, or regulatory authorities like CISA to ensure legal compliance and protect the company's reputation.
You can strengthen your everyday workflow by relying on just a few user-friendly tools. If you're unsure which security or productivity tools to choose, you can explore detailed software guides and comparisons on softer insight to find beginner-friendly options that fit your needs.
Never use the same passwords continually. A password manager will come up with and store very complicated passwords for you. Add to this Multi-Factor Authentication (MFA) and you will have a twofold security system even in case of the hacker knowing your password.
Backing up regularly is what will save you completely when you get hit by ransomware. Make sure the backups are taken to the device that will not come under infection or a very well-protected cloud storage environment. An authoritative voice like that of NIST would urge frequent backups for recovery at any point in time.
Keep your antivirus software updated. These programs run quietly in the background, catching many threats before they even reach your inbox.
Security is not a one-time project; it requires continuous effort.
Joining forces with a security training programme is a great way for anyone to really get familiar with how emergencies can be handled. Not only that, practising cyber attack scenarios with Cyber Crisis Tabletop Exercises is an excellent way to rehearse organisational response during a crisis.
Cyber threats are constantly changing, so your defences should be too. Make it a habit to review your playbook at least once a year. If you want to take your cyber attack readiness a notch higher, consider our NCSC Assured Cyber Incident Planning and Response course.
Keeping up with new scams is possible if you read extensively and use educational resources found on such sites as VPNOverview and StaySafeOnline. Staying abreast with the newest tactics that criminals are utilising is imperative.
One of the most powerful ways to counter a cyber attack ever is by doing so at a stage before a hacker identifies your network as a target. In fact, it all hinges on education, preparation, and the right tools. When non-technical users not only recognize the warning signs of an attack but also know how to isolate threats, they practically turn into a part of the securitization process.
So, be proactive in securing an opportunity to go through your backups, to change your passwords, and to read through your company’s official security policies. The steps you take today can make all the difference in not only protecting your data but also the entire organization from harmful effects of the cyber incidents.
