Hackers gained access to customer contact information such as names, addresses, cell phone numbers, and email addresses, but fortunately, SSN, date of birth, and account numbers are not accessible. The breach occurred because an employee of the bank's security team neglected and later forgot to upgrade its network servers with the double password system known as authentication two-factor for their login credentials security page have opened the door to phishing and malware attacks. The weak link in the bank's security system is simple and basic as the bank did not enable two-factor authentication, which paved the way for attachment and a huge data breach. After the bank noticed and learned about the attack and stopped it. spreads further by shutting down and blocking all paths to all 90 servers after identifying the root cause and taking action to stop the increasing losses. Later, the cybersecurity team began reviewing data on the server affected by the data breach which shut down, and no further fraud activity was reported. The average data breach costs banks $154 per account and multiplying that by 83 million accounts adds up to a staggering sum. The reported loss amounts to $12.782 billion. But the study indicates that losses from breaches tend to be even greater than those mentioned, as they add up to the loss of potential customers who end up losing business. JP Morgan announced it would spend $250 million a year to improve security by building a robust security system. The most basic additional layer of access security involves adding additional security to a user's login alongside a standard password through code generation on mobile or email. The bank security protection system without this extra layer functionality left the banks open to attacks from the other side, things could have been stopped with their extra layer of protection. JPMorgan should have examined a top-to-bottom structure aimed at eliminating security flaws in its system and could have escaped the breach and public embarrassment by examining the internal system. Department of JusticeThe Department of Justice is responsible for implementing the laws of the United States must ensure the security of thepublic against domestic and foreign threats. The 2016 DOJ attack was a successful attack on the government that resulted in the loss of nearly 200 GB of sensitive data and identities of 30,000 FBI and DHS employees and cost the U.S. economy between 57 and $109 billion in 2016. The attackers gained access through the DOJ's employer portal. by contacting the DOJ office and convincing them that he is the new employee and requesting the code that allows him to access the DOJ portal and hack the system. Employers must follow all regulations not to share authorization information over the phone or email and they must have robust firewall and security applications that will help prevent physical or cyber attacks. implementing strong corporate governanceThe strategic framework for carrying out its security operations comes into play as a subset of the overall corporate strategy around which the organization can align its IT frameworks with business frameworks to ensure that the organization continues to achieve its objectives and goals by implementing procedures to measure network and IT security. performance so that any hacks/attacks can be avoided in the future. This is created by taking into account all parties responsible for leadership, organizational and business processes as they relate to information technology. In accordance with these standards and ensuring that all necessary hardening principles are considered in the network infrastructure, security infrastructure, systems, servers, as well as social engineering attacks, must be prevented by providing high-level workshops and training to avoid phishing, email scams and viruses like Ransomware. In this paper, we single out the DOJ to discuss its IT governance plan and the security breach that occurred at the DOJ that resulted in huge chunks of sensitive information being leaked due to a cyber attack. Looking at the digital transformation taking place across the world and the amount of transactions businesses process on a daily basis, it is essential to protect infrastructure from external cyberattacks and bad guys. The stakes become increasingly high given the PII that is collected, stored and transferred during these transactions. So the question comes down to who is going to ensure that strict security measures are implemented and followed throughout the organization? This is where the need for a good IT governance framework comes into action. This can be considered as a set of standards implemented to protect the organization's users, its customers and all affected members in order to minimize the percentage of risk related to the occurrence of possible data breaches and thefts. identity and achieve exponential growth of the company. IT governance must have a clear vision of the objectives and governance frameworks that may be of interest: COBIT, ITIL, CMMI and ISO38500.
