risks. R8: The relationship between assets and boundaries in a business is that the assets are secured by the boundaries. When these boundaries have open spots to expose they are called vulnerabilities. Therefore, threat agents will try to use their attacks to reveal those assets to expose the sensitive information that they are looking for. If we don’t want this to happen to our business, we need some sort of defense such as a countermeasure to safely protect our assets. R9: Some typical…

their cyber-shenanigans. These discussions (cyber deterrence) are not scaring, nor deterring anyone. Attribution is a rather mystical thing when it comes to cyber-attacks. “Cyber related” companies offering response based services - incident response, investigations - know this very well and play up the fear to continue to sell their services. As an offensive penetration tester, I have many tricks up my sleeve that…

Dylan Bass FSEM 132 Professor Nevison 11/12/14 Internet Voting Internet voting is a type electronic voting in which voters submit their ballots, as shown by the name, by way of the Internet. There are many perceived advantages and potential issues to this method because of the simple fact that is so new and they are still working out many of the kinks. The idea behind Internet voting is that it would provide a way to improve on many of the current voting methods by making the vote processing…

significantly increased the power grids exposure to cyber-attacks (Kuder et al., 2010). Recent discoveries that hackers have inserted software into the US electrical grid, allowing the grid to be disrupted at a later date from a remote location, clearly demonstrates the fact that the utility infrastructure is quite vulnerable and that its overall mission of serving the population could be severely compromised as a result of a cyber-attack (Li et al., 2012). The power grid uses dedicated lines…

attacker to further penetrate and exploit the ZigBee network. Different types of attacks against ZigBee: ZigBee is based on 802.15.4 protocol, but however security is not very well implemented by the developers in ZigBee. This has attracted a lot of information security professional to look into the security capabilities of the 802.15.4 protocol and also the implementation of ZigBee radios in the IoT devices. The numerous attacks against ZigBee has been identified and can be classed under the…

External Attack. Is just like internal attacks only deployed from outside the network in an attempt to gain entrance and elevated privileges. These attacks seek to harm the company its employees, or customers and data. Social engineering is always a threat and exposes every user in the organization as a possible unknowing accomplish to an attack. Data breach will be the main threat in the Embassy. There is a large amount of…

hacking attacks are widespread and can affect any online services: ranging from PayPal to Sony’s PlayStation Network. A team of hackers, especially one with global support such as Anonymous advocate a policy called “hacktivism”. The concept of hacktivism usually involves using illegal means to target single issues while gaining collective support by a team to proceed with such hacks (Kelly, 2012). The attack conducted on PayPal took place in December of 2010; a Distributed Denial of Service…

In order to do this, the service level capabilities of both the Air Force and the Navy should be increased. An important cross service capability that should be developed is interoperable C2, ISR, and PED systems allowing for enhanced situational awareness, intelligence sharing, and target handoff and prosecution. Another key cross service capability are aircraft which are capable of joint munitions packages and extended flight distances…
