Join LDRA technical specialist Mark Pitchford in our new webinar. Connectivity has revolutionized embedded systems, shifting focus from standalone devices to interconnected ones, emphasizing interoperability, data use, remote capabilities, user experience, and – especially - security. Join our webinar to discover the vital role played by taint analysis in enhancing security by identifying vulnerabilities associated with the handling of sensitive data. Explore taint analysis as part of a structured software development lifecycle, connecting it with secure and safety-critical considerations. And learn of appropriately tailored tools and techniques that seamless dovetail with existing processes to meet these objectives.

HOST DISCOVERY:  In pentesting, host discovery is a crucial phase to identify live hosts on a network before further exploration and vulnerability assessment.  Various techniques can be employed for host discovery, and the choice of technique depends on factors such as network characteristics, stealth requirements and the goals of the penetration test.  TECHNIQUES: • Ping Sweeps: Sending ICMP Echo Requests(Ping) to a range of IP addresses to identify live hosts. (Quick and Common Method) But it does not work on windows server because windows firewall by default is configured to block ICMP echo Requests. • ARP Scanning: Using Address Resolution protocol (ARP) requests to identify hosts on a local network. ARP scanning is effective in discovering hosts within the same broadcast domain. • TCP SYN Ping (half-Open Scan): Sending TCP SYN Packets to a specific port (often port 80) to check if a host is live. If the host is live, it responts with a TCP SYN-ACK. This technique is stealthier than ICMP ping. • UDP PING: Sending UDP packets to a specific port to check if a host is alive. This can be effective for hosts that do not respond to ICMP or TCP probes. • TCP ACK Ping: Sending TCP ACK packets to a specific port to check if a host is alive. This technique expects no response, if a TCP RST (reset) is received. it indicates that the host is alive. • SYN-ACK PING: Sending TCP SYN-ACK packets to specific port to check if a host is alive. IF a TCP RST is received, it indicates that the host is alive. #cybersecurity #cyberdefense #ethicalhacking #cyberawareness #networksecurity

D-Link has fixed two critical vulnerabilities in the D-View 8 network management suite that could allow remote attackers to bypass authentication and execute arbitrary code. D Link is a popular brand that manufactures consumer and enterprise-grade networking hardware. D Link routers allow you to connect multiple devices to a network and manage the traffic on the network to find the shortest route between two devices that are trying to communicate with each other. The vulnerabilities are: CVE-2023-32165 CVE-2023-32169 ~First Hackers News To read the full article >>> https://lnkd.in/ggEt3ci6 #networking #management #network #brand #hardware #vulnerabilities #fhn #cybersecurity #firsthackersnews #informationsecurity #latestupdates
