While prevention is the best defense, in this article we will focus on what to do after a data breach has occurred. Read on to find out more about what steps to take to minimize further damage.
What Is a Data Breach?
A records breach is a security incident in which an attacker get entry to records without authorization. Most records breaches have the intention of stealing personally identifiable data such as credit card data to be used afterwards in criminal things to do such as credit fraud. As the quantity of digitalized data increases exponentially, the attacks end up extra frequent and more damaging.
The price of a stolen record can amount to $148, that means that a statistics breach can amount to thousands and thousands of dollars in stolen data for an organization. However damaging, a data breach is no longer an assault per se, however a end result of every other kind of attack, that lets in criminals to get right of entry to to a gadget or community to steal touchy data. Usually, the attackers reap get entry to thru spyware, phishing or damaged or misconfigured controls
Why Do Data Breaches Occur?
- Exploit the system vulnerabilities
- Exploit weak passwords
- Drive-by attacks
- Targeted malware attacks
- 5 Important Steps You Should Take After a Data Breach
1. Have a plan ready:
When a data breach or an attack is discovered is not the time to start with ad hoc decisions. You need to act fast and securely, collecting as much information as possible about what happened and why. This is why not having a detailed plan ready can cause even more damage because of decisions taken in a rush.
2. Never ignore a data breach:
Postponing to deal with a security breach is like postponing a visit to the dentist, things will not go away, and most probably the situation will worsen. The organization must perform proper disclosure, replying to inquiries from journalists, researches, and forensic analysts. Any person or entity whose data has been exposed by the data breach should be notified, in an honest, open and transparent way.
3. Find out what happened and why:
The key to prevent a future intrusion or data breach is to understand exactly what happened, which type of attack it was, what data was affected, and how the team faced the problem. A final review will help you learn what worked and what didn’t. Nevertheless, since most companies would rather focus on business and not in security forensic, it can make sense to hire an external team to conduct a forensic investigation. One of the key steps is to review the security posture and strategy, identifying possible gaps that can be exploited for future attacks.
4. Implement security measures to make it harder for the attackers to sell the data next time:
The main goal of the attackers is to use the stolen data or selling it in the dark web, with prices ranging from a few dollars for a record to several thousand for sensitive information such as passports. However, stolen data is often rendered unusable thanks to security practices such as hashing and encryption. Hashing data involves scrambling the data in such a way that it cannot be decoded back to plain text, and it is used often for password databases. Still, some hashing methods are reversible, so some organizations add a second line of defense, called a salt, consisting of random data, which further complicates decoding. Encryption only allows someone with the key to decode the data.
5. Strengthen your security:
There are several ways to strengthen the security posture, including installing security solutions to monitor the network and detect threats, such as threat management software. A couple of final tips to prevent data leaks are:
- Change and strenghten all passwords:
establish secure passwords, changing them often, and do not use the same password for several sites, as this can compromise them too. Better yet, use a password manager, a program that creates new, strong, encrypted passwords and saves them for every online account you have.
- Use two factor authentication:
this is one of the simplest ways to prevent unauthorized access, requiring a secondary six-digit code besides the right password, before granting access to the account. Keep in mind that sometimes this requires to change the code every 30 days per device.
After a data breach, it is time to learn the lesson and gather as much information as possible, using it to develop a plan and strategy to prevent further attacks. However, this is easier said than done, since the attacks get more cunning every time. Therefore, it is critical to secure the help of a third-party expert to develop and manage an effective incident response plan.
