Cybersecurity: What to Do in Case of a Data Breach

Cybersecurity is an essential part of good business practices. Cybercriminals are everywhere, and they are all looking for the same thing: to steal your information. Information is the most valuable commodity in today’s world. If it falls into the wrong hands, it could spell disaster for your company.

Therefore, strong cybersecurity practices will ensure your business stays safe from the most harmful attacks out there. Timely data safety measures can make a huge difference.

ThisIn this article, we will explore how appropriate cybersecurity practices can help you deal with a data breach. An effective response following a breach can minimize the negative impact on your business.

What Is a Data Breach?

Stéphane Nappo, Chief Information Security Office of OVHCloud, once remarked, “It takes 20 years to build a reputation and a few minutes of cyber-incident to ruin it.” Indeed, your business’s reputation can fall by the wayside by a single incident.

Thus, protecting your business’s systems is priority number one. However, there might be a situation in which cyber criminalscybercriminals compromise your system. As such, your business must react appropriately.

A common cyber incident is a data breach. A data breach consists of external actors (i.e., hackers cybcriminalser criminalsor cybercriminals) that access your system without authorization. They seek to gain control of files, passwords, or information. These criminals then utilize that information for illicit activities.

Most of the time, cybercriminals want usernames and passwords. Also, credit card information and banking details are highly desirable. Hackers can use this information to extract money from accounts. They can also use credit cards without your knowledge.

When there is a data breach, your business’s reputation suffers. Your clients may lose confidence in your business’s ability to protect their information. As a result, your business might lose credibility. After, restoring your clients’ trust can be quite a challenge.

Appropriate cybersecurity measures are necessary to avoid the negative consequences of a data breach. Therefore, the first element to consider is your system’s vulnerabilities.

A vulnerability consists of weaknesses that cybercriminals can exploit. For instance, allowing any user to log on to your network is a vulnerability. Additionally, a lack of adequate cybersecurity procedures can also lead to vulnerabilities.

Also, please be aware of suspicious emails and messages. So-called “phishing” attacks consist of seemingly authentic emails and messages sent by hackers. These messages contain links to sites set up by cybercriminals.

These sites contain keylogging technology. As such, you inadvertently provide the hackers with your password and user information. The hackers steal your credential and can then access your network.

Here is an example of how a hacker can exploit a vulnerability:

Your network does not require password access. As such, anyone can log on to the network to get internet access. In this situation, unwanted third parties can access the network and the other devices connected to it.

Now, a cybercriminal logs on to your network. These criminals hack into other users’ devices by intercepting message traffic to extract information. As a result, cybercriminals managed to steal personal data from other individuals.

In this example, the hack was preventable by implementing a password security feature. Nowadays, this feature is a standard cybersecurity practice.

Often, effective cybersecurity measures are simple. However, they can go a long way toward ensuring that hackers do not access your company’s information.

Please bear in mind that a data breach can be a costly matter. In particular, your business may go through a lawsuit as a result of a data breach. Naturally, a case is something you want to avoid.

We cannot ignore the need for adequate steps in case a data breach does happen. If a data breach does occur, your business must be ready to deal with it appropriately. Therefore, your staff must be aware of what to do in case of a suspected breach.

Let’s take a look at what you can do in case of a suspected data breach.

What to Do If Your Data Has Been Breached?

The worst thing you can do is nothing. Attempting to ignore the breach is a terrible idea. Dismissing a violation will only leave the door open for cybercriminals to exploit the stolen or compromised information.

Serene Davis of the Beazley Group has this insight to offer, “A breach alone is not a disaster, but mishandling is.” This quote underscores the importance of managing a data breach effectively when it occurs.

Here are the essential steps you can take to handle a data breach adequately.

1.    Report suspicious emails or messages

Staff must report any suspicious emails, messages, texts, or contacts at once. For instance, staff should escalate suspicious phishing emails to their supervisor. In doing so, a warning can go out to the rest of the team.

Additionally, if a staff member inadvertently comes into contact with suspicious messages, they must notify their supervisor at once. Timely reporting can prevent a hack before it takes place.

2.    Acknowledge the breach

Initially, it’s essential to acknowledge the possibility of a breach. Nothing good can come from denying a violation. Staff should immediately notify their supervisors about any suspected breaches. The objective is not to assign blame. Instead, the point is to take appropriate action to mitigate the breach.

3.    Act quickly

Taking immediate action is crucial when dealing with a breach. For example, you can disconnect all company computers from the internet while you assess the situation.

Also, calling in your IT experts will allow your business to take appropriate action. For example, you can deactivate compromised usernames and passwords right away. This action can stop hackers from gaining access to your network.

Most importantly, your business must have protocols in place. These protocols will allow your staff to act quickly once a breach takes place.

4.   Investigate

The next step is to investigate what happened. At the very least, you must have a general idea of how the attack occurred. For example, connecting a company computer to a public hotspot is a huge security risk.

At first, it might be hard to pinpoint the exact cause of the breach. Nevertheless, understanding what could have happened will help the IT team assess the situation and take appropriate action.

5.    Document everything

According to IT expert and CEO of ID Theft Recovery Eran Sinai, you must “document everything you do and everyone you talk to.” This approach is key as any information could be useful during the investigation.

Also, documenting every action taken is important for legal purposes. Additionally, documenting the incident can help distill useful lessons learned. In the end, documentation is a valuable tool. You can always find valuable insights to help you prevent future incidents.

Please keep in mind that immediate action will help you mitigate negative effects. Of course, you may not be able to stop the cyberattack fully. Nevertheless, you can help minimize the overall impact on your business and its reputation.

What to Do After a Data Breach Notification?

When a data breach occurs, your business’s reaction can help minimize its negative impact. A timely and coordinated response can help control the damage. In contrast, an inadequate response can expand the breach’s harm.

According to cybersecurity firm Norton, there are five steps you must take following a data breach.

1.    Confirm the breach

The first step is to confirm a suspected data breach. Often, cybercriminals send emails warning of data breaches. These emails usually contain links to reset passwords or “report” the data breach. Staff must not reply to these emails or click on any links.

Companies such as Google send emails to warn users of possible unauthorized use. These emails ask users to verify their account’s usage. Moreover, these emails instruct users to log on to their account and change their password. These messages never contain links.

Also, staff should report suspected breaches to the appropriate IT staff. Your IT staff can then confirm the violation by double-checking login information.

2.    Determine stolen data

The next step is to determine what data if any, criminals stole. In some cases, cybercriminals may access networks but not get any information. Nevertheless, cybercriminals usually get away with some information. Therefore, you must determine what information they got.

IT experts can dig into your network’s operating system to determine file copies and transfers. Unfortunately, this type of investigation takes some time. So, you must assume that cybercriminals compromised your business’s most sensitive data.

3.    Alert affected parties

You can proactively alert users, clients, and affiliates about a possible data breach. Your business can send out an email warning users of suspicious emails or contacts. For example, your message can ask users to ignore messages requesting them to reset their password or provide any information.

Additionally, it would help if you were transparent with other business partners. Alert them of the breach. That way, they can fortify their security measures. Above all, ensure your business partners that you are doing everything you can to handle the situation.

4.   Strengthen cybersecurity measures

Following a data breach, you must take steps to strengthen your cybersecurity measures. These steps include changing passwords, backing up data, and updating security software (firewall and antivirus).

Also, staff re-training on cybersecurity measures is key. Cybersecurity guides and meetings are essential training tools. Mainly, the aim is to reinforce appropriate cybersecurity practices. You can conduct this re-training from within your organization or hire an external consultant to provide help and insight.

5.    Get additional support

Additional support following a data breach is highly advisable. Consulting a cybersecurity expert can help you determine your network’s vulnerabilities along with other ways of strengthening them. Most importantly, you can implement practices to help your business avoid a future breach.

External consultants can work with your staff to create or update your business’s cybersecurity guidelines. Also, periodic reviews of these guidelines will ensure your team is always on the mark.

What to Do After a Data Breach?

The initial stage of a data breach is like a fire. You must first put it out before you can figure out what happened. As such, your business’s aim following a breach should be to prevent another one from happening.

Once the emergency has subsided, it’s important to communicate with business partners, suppliers, and clients. CEO of Connectwise Arnie Bellini offers this insight, “Problems such as these are best-presentedbest presented upfront and honestly. Keep everyone abreast of updates, and inform them of the steps your company and the IT team are taking to resolve the issue.”

As you can see, the objective is to be as forthcoming and transparent as possible. In doing so, your business signals confidence to business partners. You are sincere in your efforts to secure your information.

During this situation, notify your partners of the breach. Send out print letters or make phone calls. Your business partners might confuse your communication with potential cybercriminals. Also, explain the situation and the steps you are taking to remedy the situation.

Please keep in mind that you must go back to business as soon as possible. If you must go offline, try to restore your system as quickly as you can. Doing so signals that you have handled the matter. Otherwise, it might send the wrong signal to your business partners.

Also, hold any contractors accountable for their actions. You may need to call the police or involve your legal team. Do it if you must. It would be best if you took any breach seriously. Even a small, inconsequential breach can open the door to massive issues do the road.

Additionally, hire an independent, third-party IT consultant to investigate the breach. Independent consultants can provide you with an objective assessment of the situation. From there, you can determine responsibilities and hold people accountable.

Lastly, consider revising your data security guidelines. These guidelines may need updating once you complete the investigation. Consequently, the IT consultants you employ can make recommendations to improve your business’s systems. Take them seriously. The last thing you want is another breach in the future.

As Jibey Asthappan, a professor of National Security, says, “You should congratulate yourself for identifying the data breach.” After all, you can’t take steps to remedy the breach if you don’t know it happened. As a result, identifying the breach is the most important thing you can do.

 

Conclusion

A data breach is a serious matter. It can ruin your business’s reputation and jeopardize your livelihood. Whenever you or your staff suspect a breach, taking immediate action is paramount.

Initially, take the necessary steps to mitigate the situation. Mainly taking action such as changing passwords and shutting down users can cut off the hackers’ access to your network.

Then, notify your business partners about the suspected breach. In particular, warn them of possible contact from hackers. Above all, ensure them you are taking the necessary measures to minimize damage.

Lastly, a thorough investigation will help you determine when you can shore up your cybersecurity measures. Doing so will send the right message to your partners while helping you prevent a future incident.
