By adapting following method you can stop your website from getting hacked
Footprinting refers accumulating and uncovering as much as information about the target network before gaining access into any network. The approach adopted by hackers before hacking
The types of hacking stages are
A Rogue DHCP server is DHCP server on a network which is not under the control of administration of network staff. Rogue DHCP Server can be a router or modem. It will offer users IP addresses , default gateway, WINS servers as soon as user’s logged in. Rogue server can sniff into all the traffic sent by client to all other networks.
Ethical Hacking is when a person is allowed to hacks the system with the permission of the product owner to find weakness in a system and later fix them.
IP address: To every device IP address is assigned, so that device can be located on the network. In other words IP address is like your postal address, where anyone who knows your postal address can send you a letter.
MAC (Machine Access Control) address: A MAC address is a unique serial number assigned to every network interface on every device. Mac address is like your physical mail box, only your postal carrier (network router) can identify it and you can change it by getting a new mailbox (network card) at any time and slapping your name (IP address) on it.
Cross site scripting is done by using the known vulnerabilities like web based applications, their servers or plug-ins users rely upon. Exploiting one of these by inserting malicious coding into a link which appears to be a trustworthy source. When users click on this link the malicious code will run as a part of the client’s web request and execute on the user’s computer, allowing attacker to steal information.
There are three types of Cross-site scripting
The process of extracting machine name, user names, network resources, shares and services from a system. Under Intranet environment enumeration techniques are conducted.
The types of ethical hackers are
ARP (Address Resolution Protocol) is a form of attack in which an attacker changes MAC ( Media Access Control) address and attacks an internet LAN by changing the target computer’s ARP cache with a forged ARP request and reply packets.
SQL is one of the technique used to steal data from organizations, it is a fault created in the application code. SQL injection happens when you inject the content into a SQL query string and the result mode content into a SQL query string, and the result modifies the syntax of your query in ways you did not intend.
The types of password cracking technique includes
MIB ( Management Information Base ) is a virtual database. It contains all the formal description about the network objects that can be managed using SNMP. The MIB database is hierarchical and in MIB each managed objects is addressed through object identifiers (OID).
A network sniffer monitors data flowing over computer network links. By allowing you to capture and view the packet level data on your network, sniffer tool can help you to locate network problems. Sniffers can be used for both stealing information off a network and also for legitimate network management.
Pharming: In this technique the attacker compromises the DNS ( Domain Name System) servers or on the user computer so that traffic is directed to a malicious site.
Defacement: In this technique the attacker replaces the organization website with a different page. It contains the hackers name, images and may even include messages and background music.
ARP poisoning can be prevented by following methods
Mac Flooding is a technique where the security of given network switch is compromised. In Mac flooding the hacker or attacker floods the switch with large number of frames, then what a switch can handle. This make switch behaving as a hub and trmits all packets at all the ports. Taking the advantage of this the attacker will try to send his packet inside the network to steal the sensitive information.
CSRF or Cross site request forgery is an attack from a malicious website that will send a request to a web application that a user is already authenticated against from a different website. To prevent CSRF you can append unpredictable challenge token to each request and associate them with user’s session. It will ensure the developer that the request received is from a valid source.
Key-logger Trojan is malicious software that can monitor your keystroke, logging them to a file and sending them off to remote attackers. When the desired behaviour is observed, it will record the keystroke and captures your login username and password.
To synchronize clocks of networked computers, NTP (Network Time Protocol) is used. For its primary me of communication UDP port 123 is used. Over the public internet NTP can maintain time to within 10 milliseconds.
Computer based social engineering attacks are
Phishing technique involves sending false e-mails, chats or website to impersonate real system with aim of stealing information from original website.
Burp suite is an integrated platform used for attacking web applications. It consists of all the Burp tools required for attacking an application. Burp Suite tool has same approach for attacking web applications like framework for handling HTTP request, upstream proxies, alerting, logging and so on.
The tools that Burp Suite has
Denial of Service, is a malicious attack on network that is done by flooding the network with useless traffic. Although, DOS does not cause any theft of information or security breach, it can cost the website owner a great deal of money and time.
