Will and AI steal your job
won't replace all jobs, but will change nature of work -new jobs would be created to replace those lost, as with every technological shit, but it's uncertain whether these new roles will be created rapidly enough to offer job to those displaced or if these workers are even suited for these roles -for some, AI is a technology that will augment rather than replace workers
Regulations-cybersecurity
-Privacy and Personal Data Protection California Consumer Privacy Act (CCPA) -Few Federal Cybersecurity regulations -1996- Health Insurance Portability and Accountability Act (HIPPA) -1996- Gramm-Leach- Bliley Act -2002- Homeland Security Act, includes -Federal Information Security Management Act (FISMA)

-all major cloud plaforms- AWS, Microsoft Azure, Google Cloud Platform-provide access to GPU arrays for training and running machine-learning models, Google gearing up to let users use their Tensor chips -all of the necessary associated infrastructure and service are available from the big 3
what is machine learning?
-computer system learns how to performa a task rather than programmed how to do so -to learn, systems are fed huge amounts of data, which they then use to learn how to carry out a specific task -quality and size of dataset important
Protection-cybersecurity
-considerations -antivirus- check for malware-3rd party software -ad blocker -avoid dodgy plugins -back-up files- personal files in case of corruption- not connected to network -disable macros -don't just open attachments -firewall -VPN
Cybersecutity
-flash drives can have viruses and compromise data -hijacking your systems! -who borrows flash drives? -how else do you share data? -vectors for virus and malware
password strength

Artificial Intelligence
-intelligence- efficiency with which you acquire new skills at tasks you didn't previously prepare for -AI systems typically demonstrate at least some of the following behaviors associated with human intelligence: planning, learning, reasoning, problem-solving... to a certain extent, social intelligence and creativity
Why hospitals are the perfect target for ransomware
-malware works by locking your computer to prevent you from accessing data until you pay a ransom, usually demanded in BitCoin -hospitals are perfect for this extortion because they provide critical care and rely on up-to-date information from patient records -without these up-to-date info, patient care can get delayed or halted, much makes hospitals more likely to pay a ransom to avoid death and lawsuits -another reason is hospitals workers are not trained in security awareness, don't focus on cybersecurity in general. Their primary concern is HIPAA compliance, ensuring employees meet federal requirements for protecting patient privacy
What can Narrow AI do?
-organizing personal and business calendars -responding to simple customer-service queries -helping radiologists to spot potential tumors in x-rays -new applications of learning systems emerging all the time -sometimes ambitions for AI tech outstrips reality, as much potential as these systems has
Case Study
-ransomware forces shutdown -the incident led to the cancellation of 2,800 patient appointments at the NHS Trust -took 3 days to resolve -hospital are an appealing target for cyberwar
Cybersecurity- Core Fundamental
1. What do you want to protect? 2. Who do you want tp protect it from? 3. How likely is it you will need to protect it? 4. How bad are the consequences if you fail? 5. How much trouble are you willing to go through to try to prevent those consequences?
barring this, a victim has two options
1. pay the ransom 2. restore the data from backups -If formal backups don't exist, it may be possible to restore data using Shadow Copy files and other methods. Best action is for hospitals to take steps to prevent attacks and maintain weapon-grade backups -security awareness training for employees is also key to prevent them from clicking on phishing emails -hospitals can whitelist their machines to prevent ransomware installing. Involves scanning a machine to note all legitimate applications on it, then configuring it or block any other executables -configure mail services to block zip or other files that are likely to be malicious. Also, organizations should restrict permission to areas of the network -force attackers to work harder
Strategic planning- 8 related causes of security failure
1. society 2. lack of transparency 3. invisible systemic risk 4. the cultural disconnect 5. throwing money at the problem 6. poor risk-appetite statements 7. CISOs as defenders 8. Broken Accountability

Will AI kill us all?
depends on who you ask -Elon Musk- push for stronger regulatory oversight and more responsible research into mitigating downside of AI
Ransomware- A profitable business
digital extortion racket been around since 2005, it works -victims generally get infected through phishing attacks that carry a malicious attachment or instruct recipients to click on URL that downloads malware to their computer. Also, victims can get infected through malvertising if they visit a website that's serving up compromised ads -payoff can be huge -ransomeware attackers have gone further, encrypting an entire organization from accessing shared file and database. The worst ones also go after backup repositories that victim might use to restore data -FBI Flash warning- MSLI/Samas -"don't have to lock an entire network"- only crucial files to handicap an organization

What are neural networks?
key to machine learning success -are mathematical models that are able to tweak internal parameters to change what they output. A neural network is fed datasets that teach it what it should spit out when presented with certain data during training -structure and functioning of neural networks very loosely based on the connections between neurons in the brain -neural networks made up of interconnected layers of algorithms that feed data into each other. Can be trained to carry out specific tasks by modifying the importance attributed to data as it passes between the layers. During training, the weights attached to data as it passes between layers will continue to be varied until the output from the neural network is very close to what is desired. At this point, the network will have "learned" how to carry out a particular task -subset of machine learning-deep learning
reinforced learning
like rewarding a pet when it performs a trick -system attempts to maximize a reward based on its input data, basically going through a process of trial and error until it arrives at the best possible outcome
What is fueling the resurgent in AI?
machine learning and deep learning breakthroughs possible due to easy availability of data and an explosion in parallel computing power, during which the use of clusters of GPUs (graphic processing units) to train machine-learning systems has become more prevalent -clusters also available widely as cloud services over the internet -major tech firms have moved to using specialized chips tailored to both running and training machine-learning models
subset of machine learning-deep learning-neural networks
neural networks are expanded into sprawling networks with large numbers of sizable layers that are trained using massive amounts of data -have fueled the current leap forward in the ability of computers to carry out tasks like speech recognition and computer vision
What is threat modeling?
one of the most important component of staying secure online -is thinking about what data you want to protect, and who you're trying to protect it from -"What are you worried might get hacked?" -to figure out your threat mode, consider these 5 questions 1. What do you want to protect? 2. Who do you want tp protect it from? 3. How likely is it you will need to protect it? 4. How bad are the consequences if you fail? 5. How much trouble are you willing to go through to try to prevent those consequences? -overestimating your threat can be a problem too. Using technical things that are not necessary wastes time and can be putting yourself at risk. -might get a false sense of security and overlook actual threat
Narrow AI
seen around us in computers today- intelligent systems have been taught or have learned to carry out specific tasks without explicitly programmed to do so Examples Siri Vision-recognition system as self-driving cars -these systems can only learn and be taught how to do defined tasks
Evolutionary computation
sees genetic algorithms undergo random mutations and in an attempt to evolve the optimal solution to a given problem -approach have been used to design AI models, effectively using AI to help build AI -"neuralevolution"
Hackers that exposed Personal Information
since Jan. 2020, more than 20 corporate, government, and nonprofit organizations have experienced such breaches which exposed more than 899 million records -over course of a decade, the tally exceeds 11 billion records across 365 entities -nowadays, user and corporate data among a business's most valuable and most sensitive data
Phishing scams
take information from you-phone, email Case Study -Google and Facebook targeted -lost $100 million Best practice -careful of any suspicious emails -don't click on random links
supervised learning
teaches AI by using many labelled examples- machine-learning systems fed huge amounts of data, which has been annotated to highlight the features of interest. Once trained, the system can then apply these labels to new data -need both large amounts of data and computing data

How hospitals can protect themselves from cyberattacks
when ransomware strikes a hospital, the first reaction is often panic Proper response: -victims to disconnect infected systems from a network and disable WiFi and Bluetooth to prevent the malware from spreading. Victims are also to remove any USB sticks or external hard drives connected to an infected computer to prevent those being locked as well -knowing the strain of ransomware is on your system if it's well-known, there may be information published online by security firms or even tools that an bypass the encryptions -barring this, a victim has two options
What are recent landmarks in the development of AI
while modern narrow AI may be limited to performing specific tasks, within their specialism, these systems are sometimes capable of superhuman performance -many breakthroughs: -2009- Google showed its self-driving Toyota Prius could complete more than 10 journeys of 100 miles each -2011-IBM Watson won US quiz show Jeopardy!, beating two of the best players the show ever produced -Watson used natural language processing and analytics on vast repositories of data that's processed to answer human-posed questions
John Deere's promotional USB drive hijacks your keyboard
while the USB drive didn't do anything to compromise the security of devices it was connected to, the method is similar to a malicious attack -it's an HID compliant keyboard that, when connected detects what platform it's on and automatically sends a keyboard shortcut to open a browser, and then it barks the link into the address bar -John Deere's director of public affair, Ken Golden, said the distribution wasn't malicious, said they distributed same type of USB drive in the past -security experts recommends to never plug in any USB drives whose origin or contents are unknown -Hackers have put malware inside USB drives in the past, it's not not just a theoretical attack, even though John Deere's USB contained no malware
