modern day attacks against firewalls and vpns

I need some assistance with these assignment. modern day attacks against firewalls and vpns Thank you in advance for the help! The uses of VPNs help companies to access the internet at the time of travel. It is also used by the individual internet operator to secure the wireless connection. VPN is an important technological advancement for remote workers as well as organizations to share the data privately. The security issues surrounding VPNs are cracking of offline passwords, deficiency of account lockout, poor default formation, and VPN thumbprint among others (Hills, 2005). In a similar context, firewalls are the security system used to secure the flow of information between the two networks. Firewalls place a bottleneck between the networks which ensures the privacy and confidentiality of the data shared between the two networks. There are two types of firewalls as ‘packet filtering firewall’ and ‘stateful inspection firewall’. The common threats pertaining to firewalls include attacks from malicious codes such as viruses, worms, and information theft among others (Rao et al., 2011).

The technology of firewalls was first established in 1980 and since then it has undergone several modifications and alternations. Firewalls are integrated security systems designed to secure networks from unauthorized access. Firewalls are also useful for protecting the outside fire. Firewalls are also considered as a system of network security that controls the flow of traffic over the network created by a set of protocols (Brown University, n. d.). Firewalls act as a ‘software solution’ and ‘hardware appliance’. Firewalls can also be defined as security measures, which protect the local systems as well as network systems from potential threats. The two types of firewalls are packet filtering and stateful inspection firewall. A packet-filtering firewall allows the flow of packets that meets certain specific criteria.
