The Challenge!
You have been hired as a Cybersecurity Consultant for ABC, a company launching a new app. But hackers are lurking, waiting for security gaps!
Your Mission!
Help ABC follow SSDLC and build a secure app before hackers strike!
What is SSDLC?
SSDLC = Software Development Life Cycle (SDLC) + Security at Every Step!
Instead of adding security at the end, we bake it into every stage of development.
Think of it like building a house with strong locks instead of adding them later!
Why Should We Care?
80% of cyberattacks happen due to insecure software.
Companies lose millions due to breaches.
Hackers donβt wait β they find weak spots FAST!
SSDLC = Stronger Software, Safer Users, Less Headaches!
SSDLC Phase 1
Planning & Requirements
Plan for Security!
Your First Task is Identify risks before coding starts!
Questions to Ask:- What security threats could exist?
- What data will we store?
- What security rules do we need?
- Who can access what?
Example: "If we store passwords, we must encrypt them!"
SSDLC Key Activities in this Phase
Risk Assessment
Evaluate and prioritize threats based on impact and likelihood to guide security efforts.
Security Requirements Gathering
Define security controls, authentication, encryption, and compliance needs.
Threat Modeling
Identify and map out potential attack scenarios, vectors, weak points, and threats early in planning. (π§ Microsoft Threat Modeling Tool)
SSDLC Phase 2
Secure Design
Think Like a Hacker!
Threat Modeling:
Identify possible attack points before writing code!
Design security features like authentication & access control!
Example: "What if someone tries to guess passwords?" (Use multi-factor authentication!)
SSDLC Key Activities in this Phase
Secure Architecture Design
Apply security design patterns like least privilege, defense-in-depth, and secure data flow. Implement Zero Trust Architecture (ZTA) for network security.
Security Control Selection
Choose authentication (MFA, OAuth2, OpenID Connect), role-based access control (RBAC), encryption, and logging mechanisms.
Data Flow & Attack Surface Analysis
Map all external interactions (APIs, databases, third-party services). Minimize exposed attack surfaces by restricting unnecessary access points. Perform misuse case analysis to identify potential security weaknesses.
SSDLC Phase 3
Development
Write Secure Code!
Follow secure coding best practices!
Avoid common mistakes like SQL Injection, XSS, etc.
Example: "Always validate user input to prevent hackers from injecting malicious code!"
SSDLC Key Activities in this Phase
Follow Secure Coding Guidelines
Adhere to secure coding guidelines and best practices to mitigate common security vulnerabilities such as SQL injection, cross-site scripting (XSS), and buffer overflows.
Code Reviews
Conduct regular peer reviews of the code to identify and address potential security issues proactively. This involves examining the code for vulnerabilities and ensuring adherence to coding standards.
Manage Secrets & Credentials Securely
Store secrets in environment variables or secure vaults (never in code).
Dependency Management
Ensure that third-party libraries and dependencies are secure and up-to-date. This involves regularly scanning dependencies for known vulnerabilities and updating them as needed.
SSDLC Phase 4
Testing
Hunt for weaknesses before hackers do!
π οΈ Security Testing & Code Review:
Automated security scans!
Manual code reviews to spot vulnerabilities!
Ethical hacking (penetration testing)!
Example: "Test if an attacker can bypass login with a weak password!"
SSDLC Key Activities in this Phase
Static and Dynamic Analysis
Scan code for vulnerabilities without executing it and while it running to identify common issues and real-time security weaknesses.
Penetration Testing
Simulate real-world attacks to identify and rectify vulnerabilities before deployment. This involves ethical hackers attempting to exploit vulnerabilities in the system.
Security Regression Testing
Ensure that new changes do not introduce new vulnerabilities. This involves re-testing the application after changes to verify that existing security controls are still effective.
SSDLC Phase 5
Release
Launch and deploy the app securely!
π Before launching:
Security checks completed!
Secure configurations applied!
Only necessary permissions granted!
Avoid exposed admin panels, weak API security, and misconfigured servers
π A secure launch means fewer headaches later!
SSDLC Key Activities in this Phase
Secure Configuration Management
Ensure secure configurations during the deployment process to prevent misconfigurations. This involves harden server, database, and cloud configurations.
Environment Hardening
Harden the deployment environment to reduce the attack surface. This involves disabling unnecessary services, applying strict access controls, and configuring firewalls.
Deployment Security Testing
Perform final security checks before going live. This involves implementing IAM policies, MFA, and role-based access control (RBAC) to the production environment and verifying that all security controls are in place and functioning as intended.
SSDLC Phase 6
Maintenance & Monitoring
Security is NEVER over! Hackers evolve, and so must we.
Monitor for threats, update software, and patch vulnerabilities!
Incident response plans
π‘ Example: "If a new security flaw is discovered, patch it immediately!"
SSDLC Key Activities in this Phase
Apply Security Patching & Updates
Apply timely patches to address known vulnerabilities and enhance system security. This involves regularly and automated patch management to update the system with the latest security patches.
Continuous Monitoring
Implement continuous monitoring mechanisms to detect and respond to ongoing security threats. This involves using tools to monitor the system for suspicious activity in real-time.
Incident Detection & Response
Develop a comprehensive plan to respond effectively to security incidents. This involves defining roles, responsibilities, and procedures for handling security breaches.
Regular Security Audits & Compliance Checks
Conduct periodic security audits to assess and enhance the overall security posture. This involves reviewing the system's security controls and identifying areas for improvement.
Good to Know
DevSecOps
Integrate security practices into the DevOps pipeline to ensure continuous security throughout the development lifecycle. This involves automating security checks and integrating them into the CI/CD pipeline.
Threat Intelligence
Use threat intelligence feeds to stay updated on the latest threats and vulnerabilities. This involves subscribing to threat intelligence services and integrating them into the security strategy.
Security Information and Event Management (SIEM)
Implement SIEM solutions for real-time analysis of security alerts. This involves collecting and analyzing security data from various sources to detect and respond to threats.
SSDLC vs. Old SDLC
SDLC (Old Way):
Build β Test β Fix Security Later
SSDLC (Better Way):
Build Securely β Test for Security β Prevent Future Issues
π Would you rather fix leaks after your house is built or make it secure from the start?
