For over 20 years Secure Sockets Layer (SSL) has been in the market as one of the most widely-used encryption protocols ever released, and remains in widespread use today despite various security vulnerabilities exposed in the protocol. SSL/early TLS was removed as an example of strong cryptography in PCI DSS v3.1 (April 2015).
SSL v3.0 was superseded in 1999 by TLS v1.0, which has since been superseded by TLS v1.1 and v1.2. Now SSL & early TLS no longer meet minimum security standards due to security vulnerabilities in the protocol for which there are no fixes. It is critically important that entities upgrade to a secure alternative as soon as possible, and disable any fallback to both SSL and early TLS.
The best response is to disable SSL entirely and migrate to a more modern encryption protocol, which at the time of publication is a minimum of TLS v1.1, although entities are strongly encouraged to consider TLS v1.2 as not all implementations of TLS v1.1 are considered secure.
Yes but PCI DSS compliance scans from Approved Scanning Vendors check more than just SSLv3. After June 30, 2018, all entities MUST have stopped use of SSL & early TLS as a security control, and use only secure versions of the protocol. Failure to comply with this instruction will impact ASV scan results and will ultimately negatively impact on PCI compliance. A document on the PCI DSS requirements regarding SSL & early TLS can be read here.
For the convenience of LANCOM resellers looking to future proof their customer’s SSL/TLS settings, as well as pass PCI DSS testing now and into the future, we have formulated a script that will disable every instance of SSL v3.0, TLS v1.0 and TLS v1.1 leaving only the latest TLS v1.2 enabled. This script also locks down other security algorithm settings to ensure LANCOM routers will pass PCI DSS compliance scans.
*Note HTTPS WAN remote access can be enabled if a valid SSL certificate from a trusted Certificate Authority is loaded into the router. Even with HTTPS disabled you can still fully manage a LANCOM router over SSH Port 22 using the latest version of LANconfig and the CLI.
When a new PC running Windows 10 is going through its initial setup routine, also known as the Out Of Box Experience (OOBE), it is susceptible to to corruption of the routine it the unlikely event of a power interruption.
If a power interruption does occur during OOBE then there is a likelihood of the following on screen message being displayed during the next boot. Pressing OK at this state causes the PC reboot but it will show the same error message and so on in a loop.
The problem can be easily fixed by making a small change to a registry key.
The procedure is as follows.
The security loophole named KRACK is a vulnerability in the WPA2-key handshake used for secure communication in Wi-Fi networks. This vulnerability is a man-in-the-middle attack, whereby the key negotiation between a client and an access point is manipulated in such a way that an attacker can intercept the data communication.
There are three possible attack scenarios:
LANCOM are currently working on a security update for fast roaming (802.11r) and it will be released as soon as possible. The following describes where you can check to see if you are using fast roaming (802.11r) and, if applicable, how you disable it.
You can adjust this setting in LANconfig under:
“Wireless LAN -> Encryption -> WLAN encryption settings -> Wireless network X”
on the tab “Advanced -> WPA2 key management”
You can adjust this setting in LANconfig under:
“WLAN controller -> Profiles -> Logical WLAN networks (SSIDs)… -> Name of the SSID -> WPA2 key management”.
