network security vapt vulnerability assessment penetration testing pentesting services


A typical network penetration testing service comprises of simulation of real life hacking methodologies. It encompasees various security attack vectors and exploitation of potential vulnerabilities. Firewall mis-configuration, router mis-config of ACLs, incorrect configuration of switches, unpatched servers and non-compliance towards managing the desktops and laptops, are few reasons why a network is vulnerable to internal and external attacks. As a result, internal and external network penetration testing and vulnerability assessment needs to be carrid out periodically.

DoS attacks today are part of every Internet user's life. They are happening all the time, and all the Internet users, as a community, have some part in creating them, suffering from them or even loosing time and money because of them. DoS attacks do not have anything to do with breaking into computers, taking control over remote hosts on the Internet or stealing privileged information like credit card numbers. Using the Internet way of speaking DoS is neither a Hack nor a Crack. It is a whole new and different subject. This section is entirely devoted to denial of service attacks and its variants. Here, we present a broad definition of this kind of network threat, and examples of the most common attacks.

Definitions The sole purpose of DoS attacks is to disrupt the services offered by the victim. While the attack is in place, and no action has been taken to fix the problem, the victim would not be able to provide its services on the Internet. DoS attacks are really a form of vandalism against Internet services. DoS attacks take advantage of weaknesses in the IP protocol stack in order to disrupt Internet services. DoS attacks can take several forms and can be categorized according to several parameters. Particularly, in this study we differentiate denial of service attacks based on where is the origin of the attack being generated.

DoS attacks are being generated by a single host (or small number of hosts at the same location). The only real way for DoS attacks to impose a real threat is to exploit some software or design flaw. Such flaws can include, for example, wrong implementations of the IP stack, which crash the whole host when receiving a non-standard IP packet (for example ping-of-death). Such an attack would generally have lower volumes of data. Unless some exploits exist at the victim hosts, which have not been fixed, a DoS attack should not pose a real threat to high-end services on today's Internet.
