A simple explanation of what IPsec is, the network security provided by IPsec, and how to set up IPsec on Linux.
Using a VPN can provide an additional layer of security and privacy for your online activities, but whether or not a VPN is truly secure depends on several factors.The strength of the encryption used by the VPN provider is a critical factor. Most VPNs use a combination of encryption protocol...
The session layer is Layer 5 of theOSIcommunications model. It is the long-lived logical connection that persists between endpoints over time. A single session is all the back-and-forth communication between two endpoints. It helps a protocol to be more consistent and reliable. The TCP/IP pro...
A basic checksum algorithm is adequate to verify data integrity and authenticity in numerousapplications, and it can detect if any malicious tampering or accidental errors have occurred as the data is being transmitted usingpublic/private networks, clouds or hard drives. Checksums provide an early war...
At it’s core VXLAN configuration is very simple. If you are familiar with other encapsulations like GRE or IPSec this is very similar. You need a pair of routed IPs, namely loopbacks for VXLAN. Configure a VXLAN interface and set your loopback as your source address. They key difference...
Security: Look for VPNs that offer strong encryption protocols, such as AES-256, and secure tunneling protocols like OpenVPN, IKEv2/IPSec, or WireGuard. Additionally, features like a kill switch, which disconnects you from the internet if the VPN connection drops, and DNS leak protection are...
Here is a link for your reference. When you click on the "Finish installing device software" message, open the file "C:\Windows\INF\setupapi.dev" using Notepad. It should tell you which driver was last updated using the "Finish-Install" action and thus which driver is causing this.“Fini...
PPTP:This stands for “point-to-point tunneling protocol”. It is a faster connection but also not quite as secure as OpenVPN. L2TP/IPSec:which stand for “Layer 2 Tunneling Protocol” and “IP Security” respectively. It’s considered slightly more secure than PPTP but slower than OpenVPN...
(iv) Mandatory security in network Layer:IPv4 was build up when security was not an uppermost concern. Authenticating protocols like Internet protocol security (IPsec) is a part of IPv6 based protocol suite. All conforming IPv6 sessions can, therefore, be authenticated. ...
What is the purpose of IPSec? (a) to encrypt files that are stored on the hard disk. (b) to encrypt data that is sent over-the-wire. (c) to assign FS (file system) permission. (d) protection against a stolen or lost hard disk. ...
