Answer 1

Answer:

J2EE Security

• Security is a wide and complicated field, with several various technologies involved. When describing J2EE security, the developers of the J2EE specification have followed a realistic approach.
• The specification focuses on authorization within the J2EE modules instead of covering all possible facets of protection.
• The specification implies that a J2EE program can be implemented into an established protection system that incorporates features such as permission, encryption of data, and so on.
• The J2EE specification allows it possible to integrate current common protection elements into the J2EE architecture by not specifying certain dimensions of protection.
• The downside of not describing all facets of protection is that when solving any security vulnerabilities, the specification is ambiguous and incomplete.
• The complexity of the protection criteria has been improved, and the specifics more developed as the J2EE specification has grown.
• This strengthening of the protection specifications represents the maturing of the safety criteria and the acceptance by industry-standard elements such as web browsers of these criteria.
• As newer J2EE specifications are built based on the practical use of J2EE implementations, this development of the specification will certainly continue.
• For data encryption, the J2EE specification includes an environment to allow Stable Sockets (SSL). At a minimum, support for simple HTTP authentication of web-based applications is also required for the specification.

SQL Injection

• A SQL injection attack consisting of a SQL query being incorporated or "injected" through the client-to-application input details. An effective SQL injection exploit will access confidential database information, manipulate database data (Insert / Update / Delete), undertake database management activities (such as DBMS shutdown), retrieve the output of the data existing on the DBMS file system, and often issue operating system commands.
• SQL injection attacks are a category of injection attack in which SQL commands are entered into the data-plane input such that standardized SQL commands can be conducted.
• SQL injection attacks enable attackers to mimic identification, interfere with current data, create conflicts with repudiation, such as revoking transactions or modifying balances, cause all data on the server to be completely exposed, delete data or even render it unavailable, and become database server managers.
• Because of the prominence of outdated gradual development, SQL Injection is quite widespread for PHP and ASP applications. J2EE and ASP.NET applications are far less probable to be quickly abused SQL injections due to the nature of priority products accessible.
• The extent of SQL Injection attacks is constrained by the potential and innovation of the hacker, and to a lesser degree, in-depth security detection systems, such as low privilege links to the database server, etc.
