A Guide to Preventing Common Security Threats in Web Apps (1).pdf

Lots of people use PHP to make websites. It powers big websites like Facebook and WordPress. PHP is a great choice for creating websites and web apps that can change (dynamic) and grow (scalable). But why should you think about using PHP development services in India? In this blog, we'll look at five key benefits of choosing India.

This presentation aims to provide a
comprehensive guide to preventing
common security threats in web
apps, offering strategies and best
practices to safeguard digital
assets and maintain user trust in
the ever-evolving digital landscape.

3. SQL Injection Attack
Hackers exploit web app flaws by inserting bad code into
input fields to break into databases and access or damage
sensitive data. These attacks can disrupt data, manipulate
information, and compromise business and customer security.
Attackers inject harmful scripts into web pages to steal
cookies, deface sites, or redirect users to malicious sites,
compromising user accounts and important information.
Cross-Site Scripting (XSS)
Cross-Site Request Forgery (CSRF)
Understanding Common Security Threats
Trick logged-in users into unintended actions, like
changing account info or approving fake transactions,
resulting in financial loss or data leakage.

4. Exploring other
security threats on
the horizon.
MORE SECURITY THREATS
Insecure Direct Object
References (IDOR)
Flaws allow attackers to access or
modify data by manipulating
references, potentially exposing
important data and causing
unauthorized changes.
Security Misconfiguration
Leaving default passwords or
exposing unnecessary services
creates security vulnerabilities,
providing easy entry points for
attackers.
Broken Authentication and Session Management
Flaws in authentication and session management can lead to unauthorized access
to accounts and sensitive information.

5. Strategies to Prevent Security Threats
1
Validation and
Sanitization
Implementing thorough
validation and
sanitization of user
input to defend against
SQL injection, XSS, and
other code injection
attacks.
2
Prepared
Statements and
Parameterized
Queries
Always use prepared
statements and
parameterized queries
for database
interactions to prevent
SQL injection attacks.
3
Content Security
Policy (CSP)
Implementing a
Content Security
Policy to block rogue
scripts and reduce
XSS risks.

6. Anti-CSRF Tokens
Implementing anti-CSRF tokens
to verify legitimate user
requests and prevent
unauthorized actions.
Secure Authentication
Mechanisms
Secure Session
Management
Using robust authentication
methods such as multi-factor
authentication and secure
password storage to prevent
unauthorized access.
Proper session management
practices to prevent session
hijacking and replay attacks.
Best Practices for Safety

7. Least Privilege Principle
Restricting users, apps, and services to
only the permissions required for their
role to limit breach impacts.
Regular Security Audits
and Penetration Testing
Conducting security audits and
penetration testing to identify and patch
security holes.
Secure Configuration Management
Ensuring secure application and server configurations by disabling unnecessary features,
services, and accounts, and using automated tools to scan for misconfigurations.
BEST PRACTICES FOR
SAFETY - CONTD.

8. Keep Software and
Dependencies Updated
Consistently ensuring that software
is kept current and security patches
are regularly applied to minimize
vulnerabilities and enhance
protection.
Educate and Train Your
Team
Ongoing training and
knowledge sharing to help
developers identify and
mitigate new security threats.
