Types of Data Breaches
Exploit is a kind of data breach attack that benefits from software bugs or vulnerabilities, which cybercriminals use to obtain illegal access to a network and its data. Such vulnerabilities are hidden within the code of the system, and it's just a matter of time to know who will find them first: cybersecurity researchers or cybercriminals. Generally exploited software comprises the operating system, Internet browsers, and Adobe and Microsoft Office applications.
SQLI (SQL injection) is an attack that exploits weaknesses in the SQL database management software of unsecured websites to get the site reveal confidential information from the database. SQLI is one of the least complex attacks to perform, as it requires minimal technical knowledge.
Spyware is a type of malware that infects computers or networks and steals information about the user, their Internet usage, and any other valuable data. Users may install spyware without their knowledge as part of some apparently harmless downloads.
Phishing attacks operate by getting the user to share sensitive information such as their usernames and passwords. The most common phishing attack will start with an email spoofed to look like it's coming from a well-known company or a trusted coworker/friend. Clicking the supplied link will direct the user to a malicious login page designed to capture their username and password. If they don't have multi-factor authentication (MFA) enabled, the cybercriminals will have everything they need to hack into their accounts. While emails are the most common form of a phishing attack, SMS text messages, and social media messaging systems are now becoming increasingly popular.
How to a Detect Data Breach
Map your infrastructure
If you map your organization's infrastructure, you will achieve two essential purposes. It will not only give the business a full scope of how big the network is but also it will provide your security team with the advantage of knowing where to place sensors. The deeper the system is, the more difficult it is to identify cyber attacks and specifically targeted threats.
Layout sensors for detection
As mentioned above, your security team should place sensors in areas that are weak spots and throughout the network. This strategy will help to monitor network activity systematically and to analyze if the status quo is disturbed. A remote site of a distributed network is generally a weak, vulnerable spot as deploying the central security system in many locations can be expensive. However, if a company is absolutely determined to protect its data, these spots must be observed.
Analyze the data
The collected data must be observed and evaluated. The critical part is how security specialists interpret the data obtained from the network. Businesses should design zones in the infrastructure to help analysts extract significant insights from the extensive amounts of data. In this way, unusual activity, such as custom tunnels, file transfer applications, unauthorized proxies, and remote desktop protocols, can be spotted quicker. Analysts should keep an eye out for suspicious activity, for instance, machines behaving differently or a user reporting opening a malicious email.
Prepare your team for an attack
Make your company ready for an attack by testing and running a mock breach. A mock breach helps a team stay alert, teaches them what to expect, what to do, and who to contact. It also assists the business to spot critical skills gaps or train a staff member. It is much more straightforward to take proactive action to fight an attack, rather than adopting a reactive approach.
In The Event Of A Data Breach
If your company's data is leaked or breached, it's imperative that you do everything within your power to rectify the problem as soon as possible. All companies are vulnerable to a data breach, and you should be prepared for it.
