What changed from 2017 to 2021 edition

A01 – Broken Access Control

• Occurs when users can access resources or perform actions beyond their intended permissions.

• Explanation: It moved from 5th position to the top of the list. In this attack, attackers take the help of session management and try to access data from the unexpired session tokens, which gives them access to many valid IDs and passwords.

• Example: A user changes the URL from …/user/123 to …/user/124 and accesses another user's profile

• Real Breach: GitHub once had a flaw allowing users to view private repositories by manipulating access token (2012)

• Prevention:

  • Implement role-based access control (RBAC).

  • Verify user permissions on both client and server sides.

  • Use secure frameworks to handle access control.

  • Centralize access control logic.

  • Log and monitor access control failures.

  • Apply the principle of least privilege.

A02 – Cryptographic Failures

• Occurs when sensitive data (like passwords or credit card information) isn’t properly protected using encryption.

• Explanation: Shifts up one position from 3rd to 2nd position in the list. It is previously known as Sensitive Data Exposure. It focus on failures related to cryptography which often leads to sensitive data exposure or system compromise.

• Example: An app transmits login credentials over HTTP, exposing them to interception.

• Real Breach: Equifax’s breach involved unencrypted sensitive data, contributing to massive exposure (2017).

• Prevention:

  • Use strong, modern encryption algorithms like AES-256 to protect sensitive data.

  • Always encrypt data in transit using TLS (HTTPS) and data at rest to safeguard information throughout its lifecycle.

  • Store passwords using strong hashing algorithms.

  • Audit cryptographic systems regularly to detect weaknesses and vulnerabilities.

A03 – Injection

• Occurs when untrusted input is executed as part of a command or query, leading to unintended actions.

• Explanation: Slides down to 3rd position in the list. Not all applications are vulnerable to this attack, only the applications that accept parameters as input are vulnerable to injection attacks.

• Example: A login form allows SQL like admin'-- to bypass authentication.

• Real breach: The famous Sony Pictures hack exploited SQL injection to access internal databases (2011)

• Prevention:

  • Use parameterized queries or prepared statements.

  • Validate and sanitize all user inputs.

  • Avoid building SQL queries using string concatenation.

  • Apply the principle of least privilege to database users.

  • Keep your database and libraries up to date.

  • Deploy a Web Application Firewall (WAF) as an extra layer.

A04 – Insecure Design

• Refers to weaknesses that present in the designing process of a product

• Explanation: They include flaws like lack of assessment of the security measures required in a design during development phase.

• Example: A banking app allows fund transfers without verifying the recipient’s account ownership for the 2nd time.

• Real breach: Many fintech apps have been found lacking threat modeling, leading to logic flaws (2020-2023)

• Prevention:

  • Implement secure-by-design principles during development.

  • Apply rate limiting to sensitive endpoints.

  • Threat modelling for designing authentication, access controls, business logics and key flows

  • Conduct unit and integration tests to check if all critical flows of the design are safe as per the threat model

A05 – Security Misconfiguration

• Refers when security settings are improperly configured, leaving systems exposed.

• Explanation: Moved from 6th to 5th position in the list. The most common reason for this vulnerability is not patching or upgrading systems, frameworks, and components.

• Example: Default admin credentials (admin/admin) left unchanged on a production server.

• Real breach: Capital One’s AWS misconfiguration exposed over 100 million customer records (2019)

• Prevention:

  • Regularly audit and harden configurations.

  • Disable unnecessary features like directory listing or verbose error messages.

  • Using Dynamic application security testing (DAST).

  • Disabling the use of default passwords and Rotate and enforce strong credentials

  • Automated process to verify the effectiveness of security configurations time to time

A06 – Vulnerable and Outdated Components

• Refers to using outdated software components with known vulnerabilities.

• Explanation: Moved from 9th position and previously titled as Using Components with Known Vulnerabilities. It also occurs because developers frequently don’t know which open source and third-party components are present in their applications.

• Example: Using jQuery v1.7 with known XSS vulnerabilities.

• Real breach: The Struts2 vulnerability exploited in the Equifax breach was due to outdated components (2017)

• Prevention:

  • Remove unnecessary dependencies, features, components and files

  • Install components of a system only from official sources through secure channels only.

  • Properly maintain the libraries and components and regularly check for updates and upgrades for each.

A07 – Identification and Authentication Failures

• Occurs when authentication mechanisms are weak, allowing attackers to impersonate users.

• Explanation: Slide down from 2nd position and previously known as broken authentication. This normally occurs when applications incorrectly execute functions related to session management allowing intruders to compromise passwords, security keys, or session tokens.

• Example: Weak password policies allow users to set “123456” as their password.

• Real breach: LinkedIn’s 2012 breach exposed millions of weakly hashed passwords using SHA-1 (2012)

• Prevention:

  • Implementing multi-factor authentication(MFA)

  • Protecting user credentials

  • Sending passwords over encrypted connections

  • Weak passwords should not be allowed for any user

  • Credential Recovery process must be secured

A08 – Software and Data Integrity Failures

• Example: Auto-updating software pulls code from an unauthenticated source.

• Real breach: The SolarWinds attack injected malicious code into trusted updates (2020)

• Prevention:

  • Ensuring libraries and dependencies are installed from trusted repositories.

  • Unencrypted serialized data should not be sent to untrusted clients without an integrity check.

  • Use of digital signature to verify the integrity of any software or data.

  • Secure CI/CD pipelines to prevent unauthorized changes.

A09 – Security Logging and Monitoring Failures

• Occurs when security events (e.g., login attempts, error messages) aren’t logged or monitored.

• Explanation: Moved from 10th position and previously titled as Insufficient Logging and Monitoring. When applications do not properly log critical events or fail to monitor and alert on suspicious activities. This can delay detection of breaches, hinder incident response, and allow attackers to operate undetected within systems.

• Example: A brute force attack on login pages goes unnoticed because no failed login attempts are logged.

• Real breach: Target’s 2013 breach went unnoticed for weeks despite alerts from their security system (2013)

• Prevention:

  • Input validation for Login controls, access controls and server-side must be ensured.

  • Logs generated by the system should follow a particular format that can be easily stored and processed by log management solutions.

  • Regularly review logs for suspicious activity.

  • A proper implementation of an incident response plan in case of security incident

A10 – Server-side Request Forgery (SSRF)

• Occurs when an attacker tricks a server into sending requests to unintended locations.

• Explanation: Newly added risk to the list. When a web application do not validate the user-supplied URLs before fetching them, which lets the attacker to force the legit website to send a forged request to an unexpected destination, despite being protected by firewalls, access controls etc.

• Example: A file upload feature accepts a URL input to fetch the file. The attacker provides http://localhost/admin, which the server fetches, exposing internal admin data.

• Real breach: SSRF was a key vector in the Capital One AWS metadata exposure (2019)

• Prevention:

  • Sanitization and validation of all client-side input data.

  • HTTP redirections should be disabled.

  • Avoid using server-side functionality to fetch remote URLs unless necessary.

  • If URL fetching is required, limit it to internal logic with strict controls.

  • Use firewalls and network policies to prevent outbound requests to internal or sensitive systems.

In the digital world, keeping applications secure is crucial. The OWASP Top 10 is a list of the most common security risks for web applications. Understanding these risks can help you protect your applications from cyber-attacks. Let's explore the OWASP Top 10 in simple terms.

There are three new categories, four categories with naming and scoping changes, and some consolidation in the Top 10 for 2017.

1. Injection

• Injection is like letting someone fill out a form with harmful data that messes up your system.

• Detailed Explanation: This occurs when untrusted data is sent to an interpreter as part of a command or query. The attacker’s hostile data can trick the interpreter into executing unintended commands or accessing data without proper authorization.

• Example: An attacker uses SQL injection to manipulate a query by entering malicious code into a login form, bypassing authentication, and gaining access to the database.

2. Broken Authentication

• Broken authentication is like having weak locks on your doors, making it easy for intruders to get in.

• Detailed Explanation: This happens when authentication mechanisms are implemented incorrectly, allowing attackers to compromise passwords, keys, or session tokens to assume the identity of other users.

• Example: An attacker exploits weak password policies to guess or brute-force passwords and gain unauthorized access to user accounts.

3. Sensitive Data Exposure

• Sensitive data exposure is like leaving your personal information out in the open for anyone to see.

• Detailed Explanation: Sensitive data exposure occurs when applications do not adequately protect sensitive information, such as financial data, healthcare data, or personal identifiers. This can lead to data breaches and unauthorized access.

• Example: An application stores credit card information in plain text, which is then stolen by an attacker through a data breach.

4. XML External Entities (XXE)

• XXE is like letting an unknown guest into your house through a hidden door.

• Detailed Explanation: XXE occurs when an XML parser improperly processes external entities within XML documents, allowing attackers to exploit vulnerabilities to access internal files, systems, or execute malicious code.

• Example: An attacker crafts a malicious XML input containing external entity references that cause the application to expose internal files or network resources.

5. Broken Access Control

• Broken access control is like giving everyone the keys to every room in your house.

• Detailed Explanation: This happens when access control policies are not enforced, allowing unauthorized users to access restricted areas or perform actions they shouldn’t be able to.

• Example: An application uses default credentials for its admin panel, which are easily exploited by attackers.

7. Cross-Site Scripting (XSS)

• XSS is like letting someone sneak a harmful note into your notebook.

• Detailed Explanation: XSS occurs when an application allows untrusted data to be included in a web page without proper validation or escaping. This enables attackers to execute malicious scripts in the user’s browser.

• Example: An attacker injects malicious JavaScript into a comment section, which is then executed when other users view the comment.

8. Insecure Deserialization

• Insecure deserialization is like putting together a broken puzzle that can cause unexpected problems.

• Detailed Explanation: Insecure deserialization occurs when untrusted data is used to instantiate objects, leading to the execution of arbitrary code or other attacks. This can lead to remote code execution, privilege escalation, and other security issues.

• Example: An attacker manipulates serialized data to exploit vulnerabilities and execute malicious code on the server.

9. Using Components with Known Vulnerabilities

• Using components with known vulnerabilities is like building a house with faulty materials.

• Detailed Explanation: This happens when applications use libraries, frameworks, or other software components that have known security vulnerabilities. Attackers can exploit these vulnerabilities to compromise the application.

• Example: An application uses an outdated version of a library with a known security flaw, which is then exploited by an attacker.

10. Insufficient Logging and Monitoring

• Insufficient logging and monitoring is like having no security cameras to see what's happening.

• Detailed Explanation: Insufficient logging and monitoring occur when security events and incidents are not properly logged or monitored, making it difficult to detect and respond to attacks.

• Example: An attacker gains access to the system, but due to lack of logging and monitoring, the breach goes undetected for an extended period.

Understanding these risks and how they can impact your applications is crucial for building secure software. By addressing these vulnerabilities, you can better protect your applications and keep your data safe.

In the world of cybersecurity, two important concepts help organizations protect their systems from cyber threats: the MITRE Framework and MITRE ATT&CK. Let's explore what these terms mean and how they help keep our digital environments secure.

Understanding these differences helps us better appreciate the various layers of protection that keep our data and systems safe.

• Cybersecurity is like having a security system for your house, but instead of protecting your home, it protects your computer, smartphone, and all your online information from bad guys (hackers).

2. Virus

• A virus in the digital world is like catching a cold. It's a harmful program that spreads and causes problems for your computer or other devices.

3. Malware

• Malware is any software created to harm your computer or steal your information. Think of it as different types of bad guys—viruses, worms, and trojans—each with their own nasty tricks.

4. Firewall

• A firewall is like a security guard for your computer. It stands between your computer and the internet, blocking harmful stuff from getting in.

5. Phishing

• Phishing is when someone tries to trick you into giving away your personal information, like passwords or credit card numbers, by pretending to be someone you trust (like your bank).

6. Encryption

• Encryption is like putting your important information in a locked box. Only someone with the right key (password) can open it and read the information.

7. Two-Factor Authentication (2FA)

• 2FA is like using a password plus a fingerprint or a code sent to your phone to double-check that it’s really you trying to access your account.

8. Ransomware

• Ransomware is like a digital kidnapper. It locks your computer or files and demands money (ransom) to give them back to you.

9. Spyware

• Spyware is like a sneaky spy. It hides on your computer and secretly collects information about what you're doing.

10. DDoS Attack (Distributed Denial of Service)

• A DDoS attack is when a bunch of devices overwhelm a website with too many requests, causing it to crash and become unavailable.

11. VPN (Virtual Private Network)

• A VPN is like a private tunnel for your internet traffic. It hides your online activities from prying eyes and keeps your data safe when you're using public Wi-Fi.

Conclusion

Understanding these basic cybersecurity terms can help you better protect yourself in the digital world. Just like knowing how to lock your doors and windows keeps your home safe, knowing these terms helps keep your online life secure.

Imagine your computer or smartphone as a castle, filled with valuable treasures (your data and personal information). In the world of cybersecurity, the term "vulnerability" refers to any weak points in the castle walls or defences that could allow intruders (hackers) to break in and steal your treasures. Vulnerability management is like having a team of experts who regularly check the castle walls, find the weak spots, and fix them to keep the intruders out.

What is Vulnerability Management?

Vulnerability management is a continuous process of identifying, assessing, prioritizing, and fixing security weaknesses (vulnerabilities) in your IT systems. This helps to protect your devices, networks, and data from cyber-attacks.

Key Steps in Vulnerability Management

1. Discovery

   • Find the weak spots in your castle walls.

   • Explanation: This involves using tools to scan and discover all the devices, applications, and systems in your network to identify any vulnerabilities.

2. Assessment

   • Figure out how serious the weak spots are.

   • Explanation: Evaluate the discovered vulnerabilities to determine their potential impact and how easily they can be exploited by hackers.

3. Prioritization

   • Decide which weak spots to fix first.

   • Explanation: Based on the assessment, prioritize vulnerabilities based on their severity and the potential damage they could cause if exploited.

4. Remediation

   • Fix the weak spots.

   • Explanation: Apply patches, updates, or other fixes to eliminate the vulnerabilities and strengthen the defences.

5. Verification

   • Check if the weak spots are properly fixed.

   • Explanation: Verify that the applied fixes have successfully resolved the vulnerabilities without causing new issues.

6. Reporting

   • Keep a record of what was fixed.

   • Explanation: Document the identified vulnerabilities, the actions taken to fix them, and the overall improvement in security.

Why is Vulnerability Management Important?

• Protection: It helps protect your data and systems from being exploited by cybercriminals.

• Compliance: Many industries have regulations that require regular vulnerability management to ensure data security.

• Reputation: A successful cyber-attack can damage your reputation, while good vulnerability management shows you’re proactive about security.

Conclusion

Vulnerability management is like having a diligent team that constantly monitors and strengthens the defences of your digital castle. By identifying and fixing weaknesses, you can significantly reduce the risk of cyber-attacks and keep your valuable data safe.

The full onboarding checklist

Understanding log protocols in QRadar

QRadar supports multiple collection protocols and choosing the wrong one is a common source of onboarding failures. Syslog (UDP/TCP) is the most common for network devices and Linux systems. LEEF (Log Event Extended Format) is IBM's own format, used by QRadar-aware products. CEF (Common Event Format) is used by many security products including Palo Alto, CrowdStrike, and others. JDBC is used for pulling logs directly from databases. Each protocol has specific listener port requirements and parsing behaviour in QRadar.

The Universal DSM trap

When QRadar does not have a native DSM for a device, teams fall back to the Universal DSM. It will accept the logs. Events will appear in Log Activity. Everything looks fine. But fields like username, source IP, and event category will not be parsed correctly. A correlation rule looking for "failed authentication from external IP" cannot fire if QRadar does not know which raw log field contains the username. The Universal DSM is a placeholder, not a solution.

The right fix: build a custom Log Source Extension (LSE) that maps your device's raw log fields to QRadar's normalized fields. This takes time, but it is the only way to make the events usable in correlation.

Timezone — the silent data quality killer

This one causes more confusion than almost anything else in QRadar onboarding. If the log source device is in UTC but QRadar is configured to expect IST, every event timestamp will be off by 5 hours 30 minutes. This makes time-based correlation rules unreliable and makes forensic timelines inaccurate. Always verify the timezone configuration of the source device and match it exactly in the QRadar log source settings.

Validating that onboarding actually worked

Seeing events in Log Activity is not enough. True validation means confirming that events are correctly categorized (not showing as "Unknown"), that key fields like username and source IP are populated in normalized form, and that a simple test rule built on those events actually fires. Only then is the log source truly onboarded. Add it to your SIEM documentation with the onboarding date, DSM version, and the name of the analyst who validated it.

Closing

Log source onboarding is unglamorous work, but it is the foundation of every detection that comes after it. A SIEM with 200 connected log sources but 40 percent of them unparsed is not a 200-source SIEM — it is a 120-source SIEM with a misleading dashboard. Take the time to do it properly, document what you did, and validate before you move on.

Why teams make the move

The push usually comes from one of three directions — cost pressure on QRadar licensing, an organization-wide shift to Microsoft Azure, or a desire for a cloud-native SIEM that does not need dedicated on-prem appliances. Whichever the reason, the decision is rarely made by the security team alone. By the time the migration lands on the SOC's desk, it is already a business decision. The team's job is to execute it without losing detection coverage in the process.

Platform comparison at a glance

The query language gap is bigger than it looks

AQL and KQL are not just different syntaxes — they reflect fundamentally different ways of thinking about log data. In QRadar, you filter first and then aggregate. In Sentinel, KQL pipelines everything in sequence. Analysts who have spent years writing AQL need real retraining time, not a weekend workshop. Plan for at least 4–6 weeks of KQL upskilling before your team can comfortably write and tune detection rules independently.

What does not migrate automatically

This is where most projects underestimate effort. Custom DSMs built for internal or niche applications have no Sentinel equivalent — you rebuild them as custom parsers using ASIM (Advanced Security Information Model). QRadar Offenses carry a magnitude score built from relevance, severity, and credibility — Sentinel Incidents do not replicate this automatically. Your triage logic needs to be rebuilt in Analytics Rules, Playbooks, or Workbooks before go-live. Reference data (watched lists, IP ranges, user groups) stored in QRadar reference sets must be migrated to Sentinel watchlists with careful validation.

The four-phase migration approach

The parallel run — do not skip it

Running both SIEMs simultaneously for 4–6 weeks is expensive and uncomfortable. It is also the most valuable phase of the migration. This is where you discover detections that exist in QRadar but were not recreated in Sentinel. That gap — between what you think you migrated and what you actually migrated — is where real incidents go undetected in the weeks after cutover.

A useful test: take the last 90 days of QRadar offenses and verify that each one would have triggered in Sentinel with the recreated rules. Any gap is a blind spot waiting to happen.

Cost model shift — what finance needs to understand

QRadar licensing is largely fixed — you pay for EPS (events per second) capacity. Sentinel's cost scales with ingestion volume, which means a sudden spike in log verbosity directly increases your bill. Set up ingestion cost alerts in Azure and review your data connector configurations carefully. Not every log source needs to feed into Sentinel at full verbosity — workspace transformation rules can filter at ingestion and reduce cost significantly.

Closing

QRadar to Sentinel is not a lift-and-shift. It is a redesign opportunity. Teams that approach it as a rebuild — with a clear log source inventory, a rule audit, a KQL learning plan, and a disciplined parallel run — come out with a leaner, better-tuned SIEM on the other side. The ones that rush it trade one set of detection gaps for another.

SOC is a team of cyber-security dedicated to monitoring and analysing an organization’s infrastructure 24/7 and the main responsibility of the SOC team is to respond to potential or current breaches. Also, the team is responsible for scanning the security systems in real-time.

• A good SOC operator is always looking to expand the company’s security visibility by maintaining an extensive inventory of all IT assets.

• When a cyberattack occurs, the SOC acts as the digital front line, responding to the security incident with force while also minimizing the impact on business operations.

Cyber Security

Cyber security is also called computer security and information technology security.

Cyber security is the protection of computer systems and networks from attacks by malicious attackers. This may result in unauthorized information disclosure, theft or damage of hardware, software, and data.

Cyber security is important because smartphones, computers and the internet are now such a fundamental part of modern life, that it's difficult to imagine how we'd function without them. This will lead to many digital attacks associated with them.

Information Security

Information security is also called InfoSec. It is not only about securing information from unauthorized access to the data.

Information security is the practice of preventing unauthorized access, use, disclosure, disruption, modification, or destruction of information.

In short, information security is the practice of protecting information by mitigating information risks and it is a part of information risk management.

Difference between cyber security and information security

The terms Cyber security and information security are used interchangeably. As they both are responsible for the security and protection of the computer system from threats and information breaches.

Examples of Cyber security are:

• Network security

• Application Security

• Cloud Security

• Critical infrastructure

Examples of information security are:

• Procedural controls

• Access controls

• Technical controls

• Compliance controls
