According to novinkycz, on 22nd March 2022, Hacker group Anonymous released 10 GB of data from Swiss company Nestlé. This is the collective’s retaliation for continuing the company’s business in Russia.

According to Wikipedia, on 14th January 2022, a cyberattack took down more than a dozen of Ukraine’s government websites during the 2021–2022 Russo-Ukrainian crisis. According to Ukrainian officials, around 70 government websites, including the Ministry of Foreign Affairs, Cabinet of Ministers, and Security and Defense Council, were attacked.

Different types of cyber threats businesses should know

types of cyber threats

SQL Injection:

This technique involves injecting malicious SQL code into the entry field for hacking database-driven websites or websites that use dynamic SQL.

Malware attacks:

Hackers install malicious software on the victim’s system without consent in this cyberattack.

Phishing and Spear Phishing:

In this type of cyberattack, hackers send malicious emails that appear to be from genuine sources to gain personal information or influence victims to do something via these emails.

Man-in-the-middle attack (MitM):

In this cyberattack, a perpetrator intercepts the communication between client and server to either eavesdrop or impersonate someone.

Denial of Service attack (DoS):

In a DoS attack, the perpetrator shuts down the victim’s system or network to make it inaccessible to its intended users.

Distributed Denial of Service (DDoS):

In this Distributed Denial of Service attack, hackers flood the organization’s servers or networks with fake or bot users to crash the system’s normal functioning and interrupt the communication channel.

Password attack:

It is one of the most common types of cyberattacks where attackers use a mechanism to steal passwords by either looking around the person’s desk or using the sniffing technique.


It is a collection of malware-infected internet-connected devices that remains under the control of a single attacking party known as bot herders. It allows attackers to steal credentials saved on devices and gives them unauthorized access, leading to data theft and DDoS attacks.

IP Spoofing:

In this cyber attacking technique, the attacker modifies the IP address in the packet header. The receiving computer system thinks it is from a legitimate or trusted source.

Session hijacking:

In this attack, an attacker hijacks the user session. It usually starts when a user logs in to the application and ends when they log out.


In this cyberattack, the attacker encrypts the victim’s file and demands a heavy amount of money or ransom to decrypt it.

Evidently, there are various types of cyber-attacks, and businesses should leverage robust security testing to protect themselves from these malicious attacks.

What are the various security testing methods businesses can leverage?

various security testing methods

Static Application Security Testing (SAST):

SAST is a white box security testing technique where testers examine the source code to identify security defects. By using this security testing method, the security issues are identified and mitigated early

Dynamic Application Security Testing (DAST):

DAST is a black box testing technique that involves testing the application as it is running. This testing method helps identify security vulnerabilities that cyber-attackers could exploit if left unidentified.

Interactive Application Security Testing (IAST):

It is a cybersecurity testing technique that involves the usage of software instruments to assess applications in real-time. This testing method helps businesses identify and manage security risks and vulnerabilities while running web apps using dynamic testing techniques.

Red Team Assessment:

It is a broader aspect of penetration testing where the internal or external team of security experts simulate real-time attacks on the organization to determine how well an organization can defend itself from cyber attacks. Red team assessment helps to test an organization’s detection and response capabilities and also improves its security posture.

Risk-based testing:

It is the process of identifying and prioritizing potential risks associated with the software. The security testing teams prioritize the features and functions in software based on the risk of failure and its importance.

Penetration testing or ethical hacking:

In the Penetration testing method, a certified and authorized ethical hacker simulates cyberattacks to identify the security vulnerabilities in the software.

Security review: It is the process of safeguarding the entire DevOps environment by ensuring stringent security policies, strategies, best practices, procedures, and technology.

Important techniques used in security testing

security testing techniques

Testing for SQL Injection:

In this technique, testers check if it is possible to inject SQL queries into the input fields of the application without proper input validation.

Cross-site Scripting (XSS):

In this technique, testers check the web application for XSS to ensure that an application does not accept any HTML scripts. This attack happens when an attacker injects executable code within a single HTTP response.

Session Management:

Testers check the session expiration after a particular idle time after logging in and after the maximum lifetime. It also involves checking session duration and session cookie scope.

Password Cracking:

In this technique, testers try to crack the password to assess an application. They use commonly available user names, passwords, and open-source password cracking applications.

Security Misconfiguration:

It is one of the most common security flaws found in web applications due to weak or default passwords, out-of-date software, unnecessary features, and unprotected files or databases. Therefore, testers check all these aspects during the security testing.

Sensitive Data Exposure:

This issue happens when a web application fails to protect sensitive data and exposes it to end-user such as credit card/debit card information, contact information, health records, etc. Therefore, testers check the web applications to ensure that they do not expose sensitive data to the end-user.

Unvalidated Redirects and Forwards:

In this type of cyber-attacking technique, the hacker redirects or forwards the user to an untrusted website to steal information. Security testers check whether an application can stop redirection when it takes users to an untrusted link or website.

How is security testing performed in parallel to SDLC?
