- Verification Protocols: Implement procedures for verifying the identity of individuals requesting sensitive information.
6. SQL Injection
Detailed Overview:
SQL Injection (SQLi) exploits vulnerabilities in a web application’s database layer by injecting malicious SQL queries. This can lead to unauthorized access to data, data manipulation, or even complete database compromise.
Techniques:
- Classic SQLi: Injecting malicious SQL code into user input fields.
- Blind SQLi: Querying the database based on the application's responses without seeing the data.
Advanced Prevention:
- Use ORM Tools: Employ Object-Relational Mapping (ORM) tools to prevent SQL injection by abstracting database interactions.
- Regular Penetration Testing: Conduct regular security assessments to identify and fix SQL injection vulnerabilities.
7. Malware Attacks
Detailed Overview:
Malware encompasses a broad range of malicious software designed to damage, disrupt, or gain unauthorized access to systems. This includes viruses, worms, ransomware, and spyware.
Techniques:
- File-Based Malware: Delivered through infected files or software.
- Script-Based Malware: Executed via malicious scripts, often in web applications or email attachments.
Advanced Prevention:
- Application Whitelisting: Allow only approved applications to run on your systems.
- Sandboxing: Isolate potentially harmful applications or files in a controlled environment to prevent system-wide damage.
8. Cross-Site Scripting (XSS)
Detailed Overview:
XSS attacks inject malicious scripts into web pages viewed by other users. These scripts can steal session cookies, perform actions on behalf of users, or deface websites.
Techniques:
- Stored XSS: Malicious scripts are stored on the server and served to users.
- Reflected XSS: Scripts are reflected off the web server and executed immediately.
Advanced Prevention:
- Content Security Policy (CSP): Define which resources the browser is allowed to load, mitigating XSS risks.
- Input Sanitization: Filter and escape user inputs to prevent script injection.
9. Password Attacks
Detailed Overview:
Password attacks aim to gain unauthorized access by exploiting weak or stolen passwords. This includes brute-force attacks, dictionary attacks, and credential stuffing.
Techniques:
- Brute Force Attack: Trying all possible combinations until the correct one is found.
- Credential Stuffing: Using leaked credentials from one breach to access accounts on other sites.
Advanced Prevention:
- Password Policies: Enforce complex password requirements and regular changes.
- Account Lockout Mechanisms: Implement account lockout policies after a certain number of failed login attempts.
10. Denial of Service (DoS) and Distributed Denial of Service (DDoS) Attacks
Detailed Overview:
DoS and DDoS attacks aim to disrupt services by overwhelming them with traffic. While DoS attacks come from a single source, DDoS attacks are launched from multiple compromised systems.
Techniques:
- Flood Attacks: Overwhelming the target with traffic, such as HTTP requests or DNS queries.
- Amplification Attacks: Exploiting vulnerable servers to amplify the attack traffic.
Advanced Prevention:
- Rate Limiting: Control the number of requests a server will accept from a single IP address.
- DDoS Protection Services: Utilize cloud-based services to absorb and mitigate large-scale attacks.
