Application security protocols form the backbone of safeguarding software systems, protecting sensitive data, and mitigating potential threats. These are a set of rules and procedures designed to secure the communication, authentication, and data integrity of software applications. They act as crucial mechanisms in fortifying applications against various threats, including unauthorized access, data breaches, and cyber-attacks.

Importance of Application Security Protocols

Data Protection: Protocols like HTTPS, SSL/TLS encrypt data transmitted between clients and servers, safeguarding it from interception or tampering.

Authentication and Authorization: Protocols such as OAuth, SAML, and JWT enable secure authentication and authorization, ensuring that only authorized users access specific resources.

Secure Communication Channels: They establish secure channels between applications, preventing vulnerabilities that could be exploited for unauthorized access or data manipulation.

Key Application Security Protocols

1. HTTPS (Hypertext Transfer Protocol Secure): HTTPS encrypts data exchanged between a web browser and a server, ensuring confidentiality and integrity. It uses SSL/TLS protocols to establish a secure connection, crucial for secure online transactions and protecting user data.
   
   
2. SSL/TLS (Secure Sockets Layer/Transport Layer Security): The SSL/TLS protocols play a vital role in network security by safeguarding communication channels. Through encryption, these protocols protect data transmissions, ensuring that only authorized parties can access and understand the information being exchanged. Additionally, they authenticate the involved parties, guaranteeing the privacy and integrity of data shared between clients and servers.
   
   
3. OAuth (Open Authorization): OAuth serves as an authorization protocol permitting secure access to user data by third parties without the need for sharing credentials. It enables users to grant restricted access to their information, effectively controlling the resources that external entities can access.
   
   
4. OpenID Connect: Built on OAuth 2.0, OpenID Connect provides authentication services for web and mobile applications. It allows clients to verify end-user identities based on authentication performed by an authorization server.
   
   
5. SAML (Security Assertion Markup Language): SAML operates as an XML-based protocol designed for single sign-on (SSO) authentication. It facilitates the transfer of authentication and authorization data between entities, often involving an identity provider and a service provider.
   
   
6. JWT (JSON Web Tokens): JWTs are compact, URL-safe tokens used for securely transmitting information between parties. They are commonly used for authentication and information exchange in web applications.
   
   
7. Kerberos: Kerberos functions as a network authentication protocol, ensuring secure authentication among client-server applications. By utilizing tickets, it validates user identities and verifies their network access privileges to various resources.
   
   
8. LDAP (Lightweight Directory Access Protocol): LDAP, while not solely an application security protocol, is used for accessing and managing directory information. It often plays a role in authentication and authorization in various applications.

Implementing Application Security Protocols

Implementing these protocols effectively requires a strategic approach:

1. Assessment and Planning: Evaluate the specific security needs of the application, considering factors like data sensitivity and user access requirements.
   
   
2. Selection of Appropriate Protocols: Choose protocols that align with the application's requirements, ensuring compatibility and robust security measures.
   
   
3. Integration and Configuration: Integrate selected protocols into the application architecture and configure them properly to ensure seamless and secure operations.
   
   
4. Regular Updates and Monitoring: Keep protocols updated to mitigate vulnerabilities and continuously monitor their performance to detect and address any anomalies.

In a dynamic cyber security environment, it is important to test the security protocols of your web application at regular intervals. An effective approach is to check how the security system will react if the application is actually attacked.

Web application penetration testing is a simulation technique that simulates attacks against the web application to help developers and cyber security teams identify any cyber security flaws, weaknesses and vulnerabilities for timely remediation. This type of testing can be used to identify vulnerabilities across web application components and APIs including backend network, database and source code.

Types Of Penetration Testing:

Depending upon the location of attack, web application penetration testing can be classified into two types:

• External Penetration Testing: In this type, the web application is attacked from outside. The penetration test simulates the way an external attacker would launch an attack against the web application. This type of testing helps in checking firewalls and server security protocols.
• Internal Penetration Testing: In this type of penetration testing, the attacks against the web application are launched from within the organization. The testing is usually performed through LAN connections. The goal off internal penetration testing is to identify vulnerabilities that might exist within the firewall. This type of testing helps in understanding the reaction of web application security system in case of a malicious insider attack.

Another important aspect of consideration when testing web application security is level of access. Following types of web application penetration testing can be performed to test the level of access and scope of knowledge:

• Black Box Penetration Testing: This type of web application penetration testing simulates cyber security attacks that may be launched by external attackers who have no prior knowledge of targeted system.
• Gray Box Penetration Testing: This type of web application penetration testing checks the response of security systems in case of an insider attack launched by internal threat actors having user level access to certain systems.
• White Box Penetration Testing: This is a comprehensive penetration testing that simulates cyber security attacks that may be launched by a threat actor having root level or administrator access to the web application servers and data.

How Is Penetration Test Executed?

Planning:

• Define the scope of test.
• Provide required information and documentation to the tester.
• Determine success criteria of the test.

Execution:

• Run the test several times.
• Follow pre-defined success and reporting criteria.
• Create a clear & detailed report.

Post-Execution:

• Provide recommendation for remediating vulnerabilities.
• Re-test to check if remediation was effective.
• Once all tests are concluded, revert the system to original configuration.
