| Incident Response Plans | Implementing a comprehensive strategy to address security breaches or assaults. |
Why do we need to secure web applications?
Ensuring the security of online applications is of utmost importance due to various reasons:
- Protect Sensitive Information: Web applications frequently manage sensitive data, such as personal information, financial particulars, and confidential company data. Security breaches have the potential to result in the unauthorized acquisition and exploitation of data.
- Maintain User Trust and Reputation: Security events have the potential to harm an organization’s reputation and undermine user confidence, leading to lasting negative effects on the business.
- Compliance with Regulations: Various businesses are subject to legislative mandates on data protection, such as GDPR and HIPAA, which necessitate compliance with web security measures.
- Prevent Financial Losses: Cyberattacks can result in immediate financial damages due to activities such as fraudulent schemes, ransomware attacks, or disruptions to normal operations.
- Protect Against Service Disruptions: Distributed Denial of Service (DDoS) attacks have the capability to render web services inoperable, causing disruption to operations and impacting the availability of services.
Most Common Web Application Security Attacks
We have jotted down the most common Web Application Security Attacks:
- SQL Injection,
- Path Traversal,
- Cross-site Scripting,
- Local File Inclusion,
- Broken Authentication,
- Misconfigured Web Servers,
- Distributed Denial of Service (DDoS),
- Automated Threats,
- Command Injection (CMDi),
- Web Skimming Attacks, and many more.
What is Web Application Security Testing?
Web application security testing is conducted to assess and document the security measures implemented for a web application. In the current digital era, businesses are utilizing web applications to enhance user accessibility to their services. Furthermore, these online applications have become an essential requirement for organizations to facilitate communication in order to accomplish their business objectives.
Although web applications offer numerous advantages for both organizations and customers, their information visibility renders them susceptible to hackers. Hence, in order to prevent such attacks on web applications, organizations must protect their programs by implementing web application security testing techniques.
What are the types of Web Application Security Testing?
- Dynamic Application Security Testing: Dynamic Application Security Testing (DAST) is a method used to identify online application vulnerabilities that are exploitable by hackers. This testing method enhances the security of the web application by safeguarding it against the objectives established by the hacker. Furthermore, this practice facilitates the analysis of how cybercriminals can infiltrate the system’s data from an external perspective. Access to the application’s source code is not necessary during the processing of DAST, allowing for faster achievement of DAST testing.
- Static Application Security Testing: Unlike Dynamic Application Security Testing (DAST), Static Application Security Testing (SAST) focuses specifically on identifying vulnerabilities in the source code of a web application that could be exploited by a hacker. This suite of Static Application Security Testing (SAST) tools aids in the analysis of byte code, binaries, design conditions, and source code to mitigate the risk of security vulnerabilities. The inside-out approach is a widely recognized method of testing, which has gained popularity for its use in SAST practice.
- Application Penetration Testing: Conducting this form of security testing is a crucial necessity for effectively handling regulatory requirements. Automated penetration testing tools are inadequate for fulfilling this testing procedure. Therefore, it is imperative for businesses to use both manual and automated testing methodologies to identify vulnerabilities inside the regulatory framework and address concerns pertaining to business logic.
Best Ways To Secure Web Application
Enterprises can avoid such cyber-attacks. Listed below are the Best Ways To Secure Web Applications:
Use Web Application Firewalls
After the application has been launched in the market, Web Application Firewalls (WAF) might be employed to protect them from cyber-attacks. Nevertheless, the use of a Web Application Firewall (WAF) aids in safeguarding against potential risks originating from web traffic, typically occurring inside the realms of HTTP or HTTPS communication. Common features of WAF include:
- Detects application attacks
- Supports widely used protocols
- Includes algorithms and data structures
- Enables SSL termination to support both HTTP and HTTPS
- Demonstrates the concept of virtual patching.
In addition, proficient WAPs possess the ability to identify and thwart any malevolent assaults, safeguarding web applications against security vulnerabilities.
Adopt New Technologies for Application Security
The utilization of the latest technology Runtime Application Self-Protection (RASP) is a highly effective choice when implementing modifications to the application during releases. This methodology aids in minimizing human involvement and protecting web applications from potential risks.
Monitor the Security of Apps in Production
Upon the introduction of the apps into production, it is necessary to assess the application’s activity in order to ascertain the traffic patterns of users. If there is any detected behavior that is either unusually high or unusually low in terms of traffic, it could be indicative of a potential malicious attack. It is crucial to do regular checks on the logs generated by your application to detect and prevent any cyber-attacks.
Use Container Firewalls
Specific Container firewalls are used to inspect traffic within the container and help to protect the application from attacks that arise internally. Some of the components of these container firewalls are:
- Application intelligence,
- Cloud-native,
- Whitelist and Blacklist based regulations,
- Integration and management with containers,
- Compatibility with CICD (Continuous Integration and Continuous Development),
- Container threat protection,
- Container-specific packet analysis, etc.
Therefore, employing a container firewall guarantees the examination of intrusions in both inbound and outbound traffic of the container. They provide runtime protection for workloads, application services, and stacks. Adopting container firewall technology is the most effective approach to safeguard container environments against assaults.
Conduct Periodic Maturity Assessments of Application Security Processes
OWASP provides specific tools that should be utilized for evaluating the Software Assurance Maturity Model. These technologies provide a thorough examination to assess the security of your web apps and guarantee that no vulnerabilities remain undetected throughout the testing procedure.
Prioritize Remediation Based on Severity
Prompt action should be taken to prioritize the remedy of any identified security vulnerability. To minimize company risk, vulnerabilities should be promptly addressed within a designated timeframe, taking into account their severity.
Prepare Incident Response and Recovery Plan
Organizations must anticipate web application security breaches and proactively develop strategies to effectively manage them. The several stages of the Incident Response Plan comprise Identification, Containment, Eradication, Recovery, and Post Incident Activity.
- The initial Identification step should encompass the detection of all security vulnerabilities, including XSS attacks, LDAP injections, URL access restrictions failures, SQL injection attacks, and OS command injections.
- The Containment phase encompasses measures to minimize the consequences of accidents in certain targeted environments.
- In the Eradication phase, it is crucial to create robust disaster recovery plans to efficiently replace the compromised or vandalized website with a pristine page. This involves utilizing anti-virus software, modifying passwords (if applicable), or uninstalling the operating system as necessary. The Eradication phase is of utmost importance. If the program is released to end-users without eliminating numerous dangers, it might potentially harm the brand, and customer loyalty, and result in substantial economic losses.
