WPA-Personal and WPA2-Personal remain vulnerable to password cracking attacks if users rely on a weak password or passphrase. WPA passphrase hashes are seeded from the SSID name and its length; rainbow tables exist for the top 1,000 network SSIDs and a multitude of common passwords, requiring only a quick lookup to speed up cracking WPA-PSK.
The flaw allows a remote attacker to recover the WPS PIN in a few hours with a brute-force attack and, with the WPS PIN, the network's WPA/WPA2 pre-shared key (PSK). [3] Users have been urged to turn off the WPS PIN feature, [ 4 ] although this may not be possible on some router models.
Wireless security is another aspect of computer security. Organizations may be particularly vulnerable to security breaches [6] caused by rogue access points.. If an employee adds a wireless interface to an unsecured port of a system, they may create a breach in network security that would allow access to confidential materials.
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet.The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
TCP/IP defines the addresses 192.168.4.0 (network ID address) and 192.168.4.255 (broadcast IP address). The office's hosts send packets to addresses within this range directly, by resolving the destination IP address into a MAC address with the Address Resolution Protocol (ARP) sequence and then encapsulates the IP packet into a MAC frame ...
In Internet networking, a private network is a computer network that uses a private address space of IP addresses.These addresses are commonly used for local area networks (LANs) in residential, office, and enterprise environments.
A successful ARP spoofing (poisoning) attack allows an attacker to alter routing on a network, effectively allowing for a man-in-the-middle attack.. In computer networking, ARP spoofing (also ARP cache poisoning or ARP poison routing) is a technique by which an attacker sends Address Resolution Protocol (ARP) messages onto a local area network.
An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data ...
