How have cyber attacks evolved in the past quarter century?

Date:2023-01-07
Cyber attacks have become increasingly sophisticated and damaging over the past 25 years. In the mid-1990s, cyber attacks were often limited to low-level acts of vandalism, such as defacement of websites, but they have since transformed into highly complex, profit-motivated criminal activities. Tactics used by today’s malicious actors include: phishing, malware, misuse of unsecured databases, distributed denial of service (DDoS) attacks, cryptocurrency theft, and ransomware campaigns. Furthermore, these attacks are often executed by state-sponsored groups, indicating a significant increase in the resources and capability of malicious actors over the years. Today, cyber attacks have had far-reaching consequences ranging from political disruption to financial catastrophe and have generated an estimated annual damage of up to $3 trillion.

How does a satellite TV service work?

A satellite TV service works by sending signals from satellites that are placed in geostationary orbit around the Earth. The signals are then received by a satellite dish on the customer's property that is connected to a receiver. The receiver then translates the signals so they can be viewed on a TV or other device. The signals that are sent from the satellite to the customer are broadcast in a continuous stream, so customers don't need to tune in to their favorite programs. The receiver will store a listing of available channels and will tune in to these when selected by the customer. The customer can then select the programs they want to watch and see them in real-time or begin streaming them. Some satellite services may also require an internet connection.

What are the advantages and disadvantages of managed code?
Advantages: - Easier to debug and maintain since managed code is often cross-platform. - Faster compilation, since managed code is pre-compiled - Easier to deploy, as it is self-contained and does not require separate installation steps - Garbage collection, which helps to reduce memory leaks and makes it easier to write code Disadvantages: - Performance may be slower than non-managed code, as the garbage collector pauses the system while it collects memory - Not as flexible as non-managed code in terms of accessing low-level hardware and resources - Is limited to the environment it was compiled in, and therefore is not portable across platforms or hardware architectures
