Computer security

Why is it critical to perform a penetration test on a web application prior to production Implementation? To make sure no one can penetrate your web application before you put it in a live situation. 2. What is a cross-site scripting attack? Explain in your own words. Cross-site scripting is a type of computer security vulnerability typically found in web applications that enables attacks to inject client side script into web pages viewed by others 3. What is a reflective cross-site scripting attack?

A reflective attack a type of computer security vulnerability it involves the web application dynamically generating a response using non-sanitized data from the client scripts, like Java scripts or VB script, in the data sent to the server will send back a page with the script 4. What common method of obfuscation is used in most real world SQL attacks? methods, including character scrambling and masking, numeric variance and nulling, rely on an array of built-in SQL Server system functions that are used for string manipulation.

Which web application attack is more prone to extracting privacy data elements out of a database? SQL injections can be used to enter the database with administrator rights, best way to avoid this using Java on the website. 6. If you can monitor when SQL injections are performed on an SQL database, what would you recommend as a security countermeasure to monitor your production SQL databases? A well-coordinated and regularly audited security check is the best way forward. 7.

Given that Apache and Internet Information Services (IIS) are the two most popular web application servers for Linux and Microsoft Windows platforms, what would you do to identify known software vulnerabilities and exploits? Large numbers of binary planting vulnerabilities known as “dll spoofing” or “dll preloading attacks” have been discovered in third party applications running on Microsoft windows platforms. 8. What can you do to ensure that your organization incorporates penetrating testing and web application testing as part of its implementation procedures?

SQL Inject Me allows you to test for SQL injection vulnerabilities that hackers can use to hijack your data and modify the contents of a database. Some of these vulnerabilities will even allow an attacker to execute administrative operations on the database, which is disastrous. 9. What other security countermeasures do you recommend for web sites and web application deployment to ensure the C-I-A of the web application? The primary components that make up your network infrastructure are routers, firewalls, and switches.

They act as the gatekeepers guarding your servers and applications from attacks and intrusions. An attacker may exploit poorly configured network devices. Common vulnerabilities include weak default installation settings, wide open access controls, and devices lacking the latest security patches. 10. Who is responsible and accountable for the C-I-A of production web applications and web servers? The C-I-A pf production web application and web servers is the responsibility of a certified information systems security personnel in any given IT project fulfiment environment.
