We identify vulnerabilities with the ultimate goal to determine if the system can be attacked. Lisa Bock shows how attacks can occur in all layers, and evaluates website vulnerabilities with Acunetix, to test for potential attacks such as Clickjacking, Password Attacks, Buffer Overflow, or SQL Injections.
- [Voiceover] We identify vulnerabilities…with the ultimate goal…to determine if the system can be attacked.…Attacks can be active or passive against a network resource…with the hopes of exploiting a vulnerability…to achieve some end result such as denial of service;…data interception, modification, or theft.…In looking at the attack taxonomy,…attacks can occur technically in all layers…of the OSI model.…
In this graphic we see potential in the lower layers…with attacks such as DNS cache poisoning,…ICMP flooding, or IP spoofing.…Also in the higher layers such as the application layer…we see attacks such as session hijacking,…password attacks, buffer overflow, or SQL injections.…Therefore, it's really important…to identify vulnerabilities.…Our websites have many vulnerabilities…which we can fix.…
There are many tools out there…but I'm going to do trial on the Acunetix online scanner.…This is the one I'll evaluate.…I'll go to this website…and then what did was…I download and installed the free trial version.…You'll have to sign up for this.…
This course investigates the scanning tools and techniques used to obtain information from a target system, including specially crafted packets, TCP flags, UDP scans, and ping sweeps. Lisa Bock discusses how hackers can identify live systems via protocols, blueprint a network, and perform a vulnerability scan to find weaknesses. She also introduces some of the tools and techniques that hackers use to counter detection via evasion, concealment, and spoofing. In addition, learn how to reduce the threat of tunneling, a method hackers use to circumvent network security.
Note: Our Ethical Hacking series maps to the 18 parts of the EC-Council Certified Ethical Hacker (CEH) exam (312_50). This course maps to the 03 Scanning Networks domain.
