Let’s look at some common attack vectors:
- DDoS Attacks: These attacks flood a web app with traffic, making it unavailable to users.
- Brute Force Attacks: Hackers use tools to guess login details, trying millions of combinations.
- SQL Injection: Weak input validation lets attackers inject harmful SQL code, risking data exposure or database takeover.
| Attack Vector | Description | Potential Consequences |
|---|---|---|
| Session Hijacking | Attackers take over a user’s session, pretending to be the user. | They can access sensitive info and perform unauthorized actions. |
| Insecure Direct Object References | Weak handling of object references lets attackers access unauthorized data. | This can lead to sensitive info exposure and unauthorized access. |
| Injection Flaws | Poor input handling lets attackers inject malicious code into the app. | This can cause data breaches and system compromise. |

How SQL Injection Attacks Work
SQL injection attacks start with putting harmful SQL code into places like login forms. If the app doesn’t check the input well, the bad code gets run by the database. This gives the attacker control over the data and how the app works.
This can lead to stealing sensitive information, changing or deleting data, or even taking over the web server. To fight these attacks, companies need strong security steps. These include checking input carefully, using prepared statements, and limiting what the database can do. Knowing how these attacks work and securing apps can help protect against them.
