Security testing is one of the most important types of testing and its objective is to find bugs or vulnerabilities of the software or any computer or web-based application. It is being done to shield the records from an unexpected attack or intruder.
Many applications contain confidential data that can also require protection. It need to be finished periodically in order to identify the threats so that an immediately motion can be taken if an attack is being done.
The Vulnerability can be described as weak spot of any machine through which intruders or bugs can attack on the system.
If security testing has not been carried out carefully on the gadget then probabilities of vulnerabilities get increase. Time to time patches or fixes requires stopping a machine from the vulnerabilities.
Intrusion detection system basically detects the possibility of an attack,It collects the data from a number of sources, analyzes the data and finds out all possible ways to attack the system. It checks for the following:
There are four main focus areas to be considered in security testing (Especially for web sites/applications):
• Network security: This involves looking for vulnerabilities in the network infrastructure (resources and policies).
• System software security: This involves assessing weaknesses in the various software (operating system, database system, and other software) the application depends on.
• Client-side application security: This deals with ensuring that the client (browser or any such tool) cannot be manipulated.
• Server-side application security: This involves making sure that the server code and its technologies are robust enough to fend off any intrusion.
Penetration testing is on the security testing which helps in identify vulnerabilities in a system.Penetration test is an attempt to evaluate the security of a system by manual or automated techniques and if any vulnerability found, testers uses that vulnerability to get deeper access to the system and find more vulnerabilities.
The main purpose of this testing to prevent a system from any possible attacks.
Penetration testing can be done by two ways .
In white box testing, all the information is available with the testers whereas in black box testing, testers don’t have any information and they test the system in real world scenario to find out the vulnerabilities.
Due to following reasons Penetration testing must be used by the testers:
Abbreviations related to software security are:
Testing can be of following types:
The seven main types of security testing as per Open Source Security Testing methodology manual are:
SOAP – Simple Object Access Protocol that is an XML based protocol that is used to exchange information over HTTP. Web services sent XML request in SOAP format and then SOAP client sends a message to the server. The server then responds back with a SOAP message.
WSDL or Web Services Description Language is an XML formatted language that is used by UDDI. It describes the web services and the way in which they can be used and accessed.
This variety of attack makes use of the forceful looking with the URL manipulation attack. Hackers can manipulate the parameters in url string and can get the critical data which generally no longer open for public such as executed data, historic version or data which is under improvement
URL manipulation is a kind of attack in which hackers manipulate the website URL to
get the fundamental information. The data is exceeded in the parameters in
the query string by means of HTTP GET method between client and server. Hackers can
alter the information between these parameters and get the authentication on
the servers and steal the critical data.
In order to avoid this sort of attacks security testing of URL manipulation need to be done. Testers themselves can try to manipulate the URL and check for possible attacks and if discovered they can prevent these types of attacks.
Following are the three classes of intruders:
Ports are the point from where information goes in and out of any system. Scanning of the ports to find out any loop holes in the system are known as Port Scanning. There can be some weak points in the system to which hackers can attack and get the critical information. These points should be identified and prevented from any misuse.
Following are the types of port scans:
The time investment for a penetration test varies from case to case depending on the systems to be tested and the individual test requirements. Usually, the time needed ranges from a few days to several weeks. One goal of the preliminary meeting is to get enough information about the systems to be tested to estimate the optimal length for the penetration test.
Human resources on the customer’s side are usually only marginally bound. Most notably, a contact person for questions during the exploitation phase is required.
The type and amount of information needed varies with the kind of penetration test that is to be conducted. The two concepts mentioned most often are blackbox and whitebox tests. Unfortunately, those terms are not defined by a standard and can therefore mean different things, depending on who you talk to.
Red Team Penetration Testing usually recommends a whitebox test. Penetration tests performed as complete blackbox tests always suffer from the fact that third parties might get involved without their explicit consent. Providing technical information in a whitebox test scenario before the test starts also allows the penetration testers to detect security vulnerabilities that are of importance to your company even faster and more efficiently.
It should always be acted on the assumption that real, serious attackers are able to obtain the necessary information prior to their attacks, or can procure it in time. A precise determination about what information is necessary to conduct an efficient test is done individually for every client during a preliminary meeting.
Denial-of-service (DoS) attacks are usually only examined if it seems to be possible to put a system’s availability at risk with very small effort. This can for example be a misconfiguration or a program error (say, if a system crashes when it gets sent an overly long request). Attacks like this will only be performed after an explicit agreement is provided, to verify if the attack is indeed possible.
On the other hand, attacks that try to saturate the bandwidth a company has at its disposal are usually not tested, as this is always possible for attackers with sufficient resources and will also affect third-party systems. Distributed denial-of-service attacks, that usually involve hundreds, if not thousands, of zombie systems (systems that were compromised and can now be remotely controlled) cannot be simulated realistically.
A penetration test, also referred to as “pentest”, is a method of evaluating the security of a computer system or network by using simulating an attack from malicious outsiders (without any authorized means of accessing the company’s networks) but also malicious insiders (who have some level of authorized access).
The technique involves an active analysis of the system for any potential vulnerabilities that could result from poor or improper system configuration, recognized and unknown hardware or software flaws, or operational weaknesses.
The analysis is carried out from the position of a achievable hacker and can involve active exploitation of security vulnerabilities.
If you have your own IT department implemented in your security system, it is to your advantage to let an impartial third party do the audit. We provide an outsiders view on how easy/difficult it is to compromise your integrity. Having an audit report from a third party, outlining all confirmed security vulnerabilities on the network provides invaluable information to any network administrator.
The service is fast, and you will have the advantage of continually knowing how secure your network is and what you can do to improve it.
