The recent spate of attacks on companies (Lockheed Martin, Google, Sony, and Citi) inspite of their robust and state of the art security infrastructure raises the question of effectiveness of network security in computing. The problem however may not have anything to do with network security mechanisms at all, and even enhancing safeguards to infinity may not prevent future attacks. The best of firewalls, network detectors, authentication mechanisms, ...

A packet analyzer, also known as packet sniffer or network analyzer, is a computer program and hardware that intercepts and logs the traffic passing over a wireless network. It captures packets of a data stream as it flows over the network, decodes the data in the packet, and analyzes the content according to the set specifications.

Packet analyzers are used to filer suspicious traffic, and detect network intrusion attempts or misuse. It ...

With the increase in attacks on broadband, the traditional method of protection such as firewalls and basic authentication becomes insufficient to protect against unauthorized entry and fraud.

Analysts at Dimension Data reveal that notwithstanding the best of safeguards such as firewalls and authentications in place, as many as 73 per cent of all network devices have at least one known security vulnerability, which is akin to leaving ...

Password Cracking is one way hackers and other intruders make unauthorized entry to networks, to perform their nefarious acts such as data theft, malware attacks, DDoS attacks, and more.

Cracking a password can be as simple as the intruder searching the garbage for that sticky note with the password written on it, or a disgruntled employee spilling the beans in the course of a conversation, either deliberately or inadvertently. Methods that ...

SQL Injection attacks pose a serious threat to web applications, especially those applications that generate dynamic content through a database back-end. Such attacks occur when hackers exploit security vulnerability in the database layer of an application. The hackers use code injection technique, or embedding one programming or scripting language inside another to inject their own SQL commands into the commands issued by the database.

SQL injection attacks are commonplace, and even websites ...

WPA or Wi-Fi Protected Access is a standard security protocol implemented by Wi-Fi alliance to secure wireless computer networks through encryption and authentication. It is an improvement over the earlier WEP or Wired Equivalent Privacy standard, resolving much of its weakness and offering greater security. WPA2 or wi-fi Protected Access II is a further advancement of the WPA standards. WPA implements most of the IEEE 802.11i standards and WPA 2 ...

Cloud computing is the concept of storing, managing, and processing data and accessing hardware using a network of virtual remote servers rather than using the local network or desktop PC. Cloud computing turns the traditional desktop PC into a “thin client” that uses the internet to access applications, run programs, and store data.

The three major services of cloud computing include SaaS, PaaS, and IaaS.-

• SaaS, the acronym for Software ...

Late at night on April 26 2011, Sony confirmed everyone’s worst fears: Sony PlayStation Network had been hacked by an outside agency, and secure data of more than 77 million registered accounts had been compromised. Sony has recently confirmed that credit card numbers of 12,700 non-US users had been hacked into, and that the debit card details of 10,700 users in Austria, Germany, Spain and the Netherlands had been compromised as well. Rumors ...

Pod slurping uses the iPod to, well, slurp confidential information from a security compromised network.

It works like this: an iPod can store more than 80 gigabytes of data, and it is easy for an unscrupulous iPod user to gain access to huge amount of confidential information. The iPod user simply uploads data from an organization’s network to the iPod, or to any other removable storage device. About 100 MB of data from the ...
