Amazon's Newest Security Feature 

Amazon is now using a new CPU called the Graviton4. It is a new processor that is arm-based chip and aims to protect against branch prediction attacks, as well as other new features. The chip supposedly provides up to thirty percent higher quality compute performance, and 75 percent more memory capacity. The most interesting feature of this chip is the new Branch Target Identification, also known as BTI. The BTI is designed to protect against sophisticated cyber threats, and mitigates against branch prediction attacks. The BTI guesses the outcome of a threat, then does any work needed to protect the security, and if that work is unneeded after the outcome, the work is undone. Which I think is pretty cool.

Major Tech Outage On July 19th, 2024 a global tech outage occurred. This outage hit many different types of businesses anywhere from airlines to small businesses. The culprit of this major outage was a software update for Microsoft Windows. This update was issued from a company called CrowdStrike, and the reason for the update was for the company's cybersecurity. CrowdStrike is a company that provides businesses with preventing security breaches, and is a major provider, with more than 500 customers on the Fortune 1000 list. Multiple people reached out to me personally, and let me know their own workplace has been affected. The major outage that occurred in places all over the world is said to not be an attack, but it leaves me wondering if that is true or not. You can find probably over a hundred articles on this topic, but here are a couple articles that I used.  https://www.theverge.com/2024/7/19/24201864/crowdstrike-outage-explained-microsoft-windows-bsod https://www.cnn.com/bu...

 AT&T Cyberattack Today July 12, 2024, AT&T came out with an announcement that data has been breached from almost all customers of the giant brand. The attack occurred in 2022 and lasted over five months. The data leak impacted around 109 million accounts. I believe the number of people affected could be around 200 million, because usually there is more than one phone on an account. AT&T does not believe the data leaked is publicly available, and they state that "the data does not contain the content of calls or texts, personal information such as Social Security numbers, dates of births, or other personally identifiable information." But I find that last statement hard to believe. AT&T also said the data compromised includes calls and texts, which contradicts other statements they have made. This means people can see texts and the phone number associated with those texts, and then go online to find out whose number that is. This data breach calls attention to...

 Cybersecurity Budgets Are On The Rise I found an article stating corporate cybersecurity budgets have increased almost 60 percent just this year. You can thank the rise of cyber threats, as well as the increase in the desire for artificial intelligence for this budget increase. Out of the organizations in this research, 61 percent said they have experienced a cybersecurity incident within the past two years. More than half the organizations state the budget increase is based on the proven effectiveness for reducing security incidents, as well as assessing risks and threats that those organization face. These methods to find better security practices also costed an average of 26 million dollars per company.  These numbers show the importance of the need to keep up with the fast changing world of technology. With new ways of attacking a company coming with new technology, as well as the rise of AI. You can read the article here: https://www.cfodive.com/news/60-corporate-cy...
