?? ?????????????????????????? ???????? ???? ?????? ??????: ???????????? ?????????? ???????????? ?? The weakest link in your supply chain can compromise your entire system! In a supply chain attack, hackers infiltrate organizations through trusted third-party vendors, software providers, or hardware manufacturers. These attacks can lead to data breaches, malware injections, and operational disruptions. ?????? ?????????? ???? ???????????? ?????????? ??????????????: 1. ???????????? ????????????????????: Attackers exploit weaker security in third-party vendors. 2. ?????????????????? ???????? ??????????????????: Malware is introduced through legitimate software updates. 3. ???????????????? ??????????????: Compromised hardware is inserted into the supply chain. ???????????????????? ?????????? ???? ???????????? ?????????????? ?????????? ??????????????: 1. ?????????????? ?????????????? ???????? ??????????????????????: Identify vulnerabilities in your third-party relationships. 2. ?????????????????? ???????????? ???????????? ????????????????????: Set clear security standards and conduct regular audits of suppliers. 3. ?????????????? ????????????????????: Use attack surface management tools to monitor for anomalies. 4. ?????????? ???????? ?????????? ????????????????????: Limit access based on the principle of least privilege—assume threats can arise from anywhere. 5. ?????????????? ??????????????????: Train your team to recognize potential threats and practice good cybersecurity hygiene. 6. ?????????????? ???? ???????????????? ???????????????? ????????: Prepare a tailored plan for supply chain incidents—practice makes perfect! ???

?? ?????????????????????????? ???????? ???? ?????? ??????: ???????????????? ?? Sniffing is the act of intercepting and monitoring network traffic without permission. Attackers use tools called sniffers or packet analyzers to capture sensitive information like passwords, usernames, or private data as it moves across a network. This can happen on both wired and wireless networks, especially if the data isn't properly secured with encryption. ????? Imagine you’re connected to a public Wi-Fi at a coffee shop ??. An attacker nearby uses a sniffer to intercept all the data being transmitted on that network. If the data isn’t encrypted (like using HTTP instead of HTTPS), the attacker can easily capture your login credentials or even banking information ??. ??? ???????? ?????????????????? ???? ?????????????? ?????????????? ????????????????: 1.? ?Use strong encryption like TLS (Transport Layer Security) to secure communications. ?? 2.? ?Set up VPNs (Virtual Private Networks) to protect data, especially on public or unsecured networks. ????? 3.? ?Strengthen security with network access controls and require authentication (such as 802.1X) for devices connecting to the network. ?? 4.? ?Implement Multi-Factor Authentication (MFA) to add another layer of protection for user accounts, even if the network is compromised. ???? 6.? ?Regularly update and patch network devices to close any security gaps that attackers could exploit. ???? ???????????????????????? ???????????? ???? ???????????????? ????????????????????: 1.? ????????? ???? ???????????????????? ??: Data transmitted in plaintext without encryption (like TLS) is vulnerable to interception by attackers. 2.? ????????? ?????????????? ?????????????????????????? ??: Poorly configured networks, such as open Wi-Fi or improperly set switches, increase exposure to sniffing attacks. 3.? ????????????????? ???????????????? ?????????????????? ?: Using outdated protocols (like HTTP or WEP) fails to provide adequate protection against data interception. 4.? ??????????????????? ???????????? ???????????????? ??: Public Wi-Fi networks without VPNs or encryption are prime targets for attackers using packet sniffing tools. 5.? ????????????????????????? ?????????????? ???????????? ??: Inadequate access controls and authentication allow unauthorized users to connect and sniff network traffic.
