Security and Vulnerability assessments

There are two levels of vulnerability assessments we offer.
Level 1: (Most Popular) Asses the broad vulnerabilities of your network with a brute force attack    searching for un-encrypted access to files, shares, personal information, administrative access to    machines though weak usernames and passwords. (Usually takes a half day)
Deliverables: A list of all machines and vulnerabilities along with all usernames, passwords, and shares    uncovered in the attack. We provide recommendations to repair any vulnerabilities.
Level 2: We use the brute force attack with customized usernames and passwords tailored to your    organization. We add a dictionary attack against key machines to uncover any sensitive data    elements.
Deliverables: A list of all machines and vulnerabilities along with all usernames, passwords, and shares    uncovered in the attack. We provide recommendations to repair the vulnerabilities.

Different type of vulnerabilities/attacks that can be performed against your network.

1) Denial of Service
    A Denial of Service (DoS) attack is an attempt by an attacker to prevent legitimate     users from accessing a service.
         a. SYN Flooding
               i. An attack that sends TCP connection requests faster than a machine can                   process them, creating a DoS (Denial of Service) attack by locking up the                   resources on the victim machine.
         b. ICMP Flooding
               i. Sending very large PING packets to a vulnerable target machine, usually                   causing the victim machine to reboot.
2) Password Cracking
         a. Dictionary Attack
              i. Using a list of well-known usernames and passwords and running the list                  against the login system or a stolen password file to crack usernames and                  passwords on a system.
         b. Brute Force Attack
              i. Similar to a Dictionary Attack, but instead tries all possible characters and                  combinations of them. This kind of attack guesses almost all passwords,                  even though it’s a very lengthy process to do so.
3) Man in the Middle Attacks
         a. This is when an attacker intervenes in a session created between a user and               any other party (another PC, server, etc.) that user is connected to in order               to read, insert, or modify the communications between the two parties. This               is also done without either party noticing anything abnormal going on.
4) Spoofing
         a. When an attacker appears as another source while performing any attacks or               fraud on a victim. Ex. IP Spoofing = Using someone else’s IP to mask yourself               as the other person.
5) Session Hijacking
         a. This is when an attacker takes over a TCP session (Network communication)              between two computers.
6) Teardrop Attack
         a. An exploitation of specific operating systems that exploits using overlapping              fragmented packets to freeze and/or reboot a machine.
7) Protocol Exploitation
         a. When an attacker exploits a weakness in an operating system, software piece,              or communication protocol to their advantage to take over a PC, server,              router, entire network, etc.
8) Social Engineering
         a. When an attacker uses weak-minded employees to gain access to passwords,              usernames, locations of servers, etc. through social interaction, phone calls, or              e-mails.
9) Disgruntled Employees
        a. Employees of your place of business that decide to wreak havoc on your             network, PC, etc for their own reasons.
10) DHCP Poisoning
        a. Setting up a DHCP server on a network that shouldn’t be on that specific             network (AKA Rogue DHCP Server) in order for the attacker to distribute IP’s of             their choosing to trap traffic, perform redirection, etc.
