Whether you’re protecting pacemakers in elderly patients or safeguarding data for the Equifax hack, cybersecurity is a field that matters. But it’s not a career for the faint of heart. The complexities, growth potential and puzzles of the discipline can make it challenging to master. But it also offers a rewarding opportunity to protect people and companies against attacks that can impact the physical world.
Cybersecurity is the field that protects Internet-connected systems, devices, networks and data from unauthorized access and criminal use. It’s an ever-evolving domain, as new technologies and attack techniques continue to emerge. And it’s critical to the operation of modern businesses because data breaches can have significant financial costs and damage reputations.
There are a wide range of cybersecurity initiatives that need attention, including securing physical infrastructure such as routers and networks, securing cloud services, developing a zero trust framework and establishing policies for third parties. In addition, organizations need to develop a culture of cybersecurity that involves the entire workforce.
The most common threat to a company’s security is malware, which can include viruses, worms and spyware, as well as ransomware, where hackers lock a business out of its data until a ransom is paid. Antivirus software is a must, and tools that can help block phishing attempts and sift through fake websites are helpful as well. Encryption can also prevent malicious attacks by obscuring the data a business holds so that snooping hackers can’t read it. MDR
