Strong demand for cybersecurity workers is continuing even as big technology companies lay off thousands of employees.

That’s not a big surprise, as cybersecurity is seen as one of the more resilient areas for tech investment in a more cautious economic environment — though even it is not immune from the tech sector slowdown. But it is an area for young professionals, college students, and workers looking to make career transitions to focus on as the tech sector’s labor force contracts significantly for the first time in a decade, from the largest companies to the venture-backed startup community.

There were 755,743 online job postings in cybersecurity as of December, according to new research from cybersecurity workforce analytics site CyberSeek, created through a partnership of the National Initiative for Cybersecurity Education, CompTIA, and labor market research firm Lightcast. That did represent a year over year decline in postings, from 769,736 in the 12-month period ending December 2021. But with a supply-demand ratio currently at 68 workers per 100 job openings, the nearly 530,000 more cybersecurity workers need in the U.S. went up year over year.

The researchers say the data reinforces a trend that has existed for years now and will persist: the shortage of cyber talent. If all those positions are filled, that’s a labor force positioned for huge growth. The total number of employed cybersecurity workers was estimated at 1.1 million, steady year over year.

Here are the top things to know about pursuing a career in cybersecurity.

How to ‘major’ in cybersecurity during college

When looking for a job, you’re guaranteed to be asked what major you studied in college. While cybersecurity is not a common major for colleges to offer, there are a large range of related majors that can make you a potential candidate for a job in this field. The most obvious comps are computer science, information technology, software development, and even business management.

“The more that you can find either courses or other educational opportunities while you’re in school, to learn both the fundamentals of IT and the fundamentals of cybersecurity, as well as some of the specific high-value, high growth skills that employers are increasingly demanding, that’s going to best set you up for success when you enter the job market,” said Will Markow, vice president of applied research at Lightcast.

However, it’s not as much about a specific major studied as the skills which employers are attempting to identify.

The question that candidates need to be prepared to answer isn’t what they majored in, but, “What have you learned during your degree that prepares you for a career in cybersecurity?” Markow said.

Obtaining technical skills after college

Technical skills in information security theories, network administration, and IT is some of the primary knowledge that candidates need, while strong soft skills like communication and collaboration are additionally important. But whether you are a college student or graduate already in the job market, there are plenty of other opportunities to gain the skills you need to enter this field, primarily through certifications.

Non-profit trade association CompTIA’s Security+ is the most in-demand entry level credential for cybersecurity professionals, according to Markow. By receiving the Security+ certification, CompTIA states that professionals will acquire the skills to assess an environment’s security, monitor hybrid environments, respond to security events and more. Other commonly requested certifications are EC-Council’s Certified Ethical Hacker training and GIAC’s Security Essentials (GSEC) training.

“Cybersecurity is a heavily sophisticated field, and employers place a lot of weight on certain credentials,” Markow said.

How to get started in job search

Some of the most common entry-level positions include cybersecurity analysts, cybersecurity technician specialists, and cybercrime analysts. These positions focus more on what is defined as reactive work, for example, learning about the types of threats that organizations are facing, and identifying when threats need to be investigated and remediated.

As professionals progress in a cybersecurity career, the goal is to gradually take on more proactive work helping organizations design secure digital infrastructure.

There are many opportunities for existing tech professionals to make the move into this field, with common launch pads including other IT roles such as network administration, software development, systems engineering and even IT support; and by targeting the lower-level cyber positions.

“Since those roles often have lower barriers to entry than some of the more advanced positions in the field, and if you are able to target one of the certifications and obtain one of those entry level certifications from CompTIA, or other providers, then you will have the greatest chance of finding an opportunity in one of those roles,” Markow said.

The approach of first entering through the broader IT job market can work for new labor force entrants as well. “If you’re starting from complete scratch, it’s often useful to target some of those positions that can serve as launching pads into the core cybersecurity roles,” Markow said.

Jobs will often pay over $100,000

Cybersecurity jobs pay well, too.

The average salary ranges between $100,000-$120,000.

There are going to be differences in pay based on experience level, as well as the specific role.

“You probably won’t start at $110,000,” Markow said. “You might start somewhere in the $70,000-$90,000 range, depending on what part of the country you’re in. But as you gain experience in and advance within cybersecurity, the salaries become progressively larger and more appealing.”  

Where the jobs are concentrated also varies region to region, and by sector. The new research found public sector cybersecurity job demand growing by 25% to 45,708 postings in 2022, a faster growth rate than in the private sector, but still far fewer jobs overall compared to the private sector’s 710,035 listings. Lightcast says that public sector job demand trend isn’t a one-year phenomenon, growing by 58% over the past three years in all. Related to that, the Washington, D.C. metro area accounted for 19% of all public sector domestic cybersecurity job listings.

Tesla launches refreshed Model Y in China to fend off domestic rivals

Tesla launched a revamped version of its Model Y in China.

Tesla

Tesla on Friday announced a revamped version of its popular Model Y in China, as the U.S. electric car giant looks to fend off challenges from domestic rivals.

The Model Y will start at 263,500 Chinese yuan ($35,935), with deliveries set to begin in March. That is 5.4% more expensive than the starting price of the previous Model Y.

A spokesperson for Tesla China said that the new Model Y is only open for pre-sale in the Chinese market, rather than being launched globally.

Tesla’s Model Y refresh comes after the auto giant this month reported its first ever annual decline in overall deliveries for 2024.

Elon Musk’s electric vehicle firm is facing heightened competition around the world, from startups and traditional carmakers in Europe. In China, the company continues to face an onslaught of rivals from BYD to newer players like Xpeng and Nio.

Jason Low, principal analyst at Canalys, notes that the Tesla Model Y was the best-selling EV in China in 2024 and that the popularity of the car “remains high.” However, he noted that the competition in the sports utility vehicle (SUV) segment with vehicles priced between 250,000 yuan and 350,000 yuan “has been fierce.”

“Tesla must showcase compelling smart features, particularly a unique but well localized cockpit and services ecosystem,” as well as “effective” semi-autonomous driver assistance features “to ensure its competitiveness in the market,” Low added.

Tesla is offering a number of incentives for customers to buy the Model Y including a five-year 0% interest financing plan.

The new Model Y can accelerate from 0 kilometers per hour to 100 kilometers per hour in 4.3 seconds, Tesla said, exceeding the speed capabilities of the previous vehicle. The Model Y Long Range has a further driving range on a single charge versus its predecessor.

Tesla has not introduced a new model since it began delivering the Cybertruck in late 2023, which starts at nearly $80,000.

Investors have been yearning for a new mass-market model to reinvigorate sales. Tesla has previously hinted that that a new affordable model could be launched in the first half of 2025.

Despite Tesla’s headwinds, the company’s stock is up nearly 70% over the last 12 months, partly due to CEO Musk’s close relationship with U.S. President-elect Donald Trump.

Taiwan Semiconductor Manufacturing Co. posted December quarter revenue that topped analyst estimates, as the company continues to get a boost from the AI boom.

The world’s largest chip manufacturer reported fourth-quarter revenue of 868.5 billion New Taiwan dollars ($26.3 billion), according to CNBC calculations, up 38.8% year-on-year.

That beat Refinitiv consensus estimates of 850.1 billion New Taiwan dollars.

For 2024, TSMC’s revenue totaled 2.9 trillion New Taiwan Dollars, its highest annual sales since going public in 1994.

TSMC manufacturers semiconductors for some of the world’s biggest companies, including Apple and Nvidia.

TSMC is seen as the most advanced chipmaker in the world, given its ability to manufacture leading-edge semiconductors. The company has been helped along by the strong demand for AI chips, particularly from Nvidia, as well as ever-improving smartphone semiconductors.

“TSMC has benefited significantly from the strong demand for AI,” Brady Wang, associate director at Counterpoint Research told CNBC.

Wang said “capacity utilization” for TSMC’s 3 nanometer and 5 nanometer processes — the most advanced chips — “has consistently exceeded 100%.”

AI graphics processing units (GPUs), such as those designed by Nvidia, and other artificial intelligence chips are driving this demand, Wang said.

Taiwan-listed shares of TSMC have risen 88% over the last 12 months.

TSMC’s latest sales figures may also give hope to investors that the the demand for artificial intelligence chips and services may continue into 2025.

Foxconn, which assembles Apple’s iPhones, reported its highest-ever fourth quarter revenue this week, as it notched strong demand for AI servers.

Meanwhile, Microsoft this month said that it plans to spend $80 billion in its fiscal year to June on the construction of data centers that can handle artificial intelligence workloads.

Supreme Court set to hear oral arguments on challenge to TikTok ban

Tik Tok creators gather before a press conference to voice their opposition to the “Protecting Americans from Foreign Adversary Controlled Applications Act,” pending crackdown legislation on TikTok in the House of Representatives, on Capitol Hill in Washington, U.S., March 12, 2024.

The Supreme Court on Friday will hear oral arguments in the case involving the future of TikTok in the U.S., which could ban the popular app as soon as next week.

The justices will consider whether the Protecting Americans from Foreign Adversary Controlled Applications Act, the law that targets TikTok’s ban and imposes harsh civil penalties for app “entities” that continue to carry the service after Jan.19, violates the U.S. Constitution’s free speech protections.

It’s unclear when the court will hand down a decision, and if China’s ByteDance continues to refuse to divest TikTok to an American company, it faces a complete ban nationwide.

What will change about the user experience?

The roughly 115 million U.S. TikTok monthly active users could face a range of scenarios depending on when the Supreme Court hands down a decision.

If no word comes before the law takes effect on Jan. 19 and the ban goes through, it’s possible that users would still be able to post or engage with the app if they already have it downloaded. However, those users would likely be unable to update or redownload the app after that date, multiple legal experts said.

Thousands of short-form video creators who generate income from TikTok through ad revenue, paid partnerships, merchandise and more will likely need to transition their businesses to other platforms, like YouTube or Instagram.

“Shutting down TikTok, even for a single day, would be a big deal, not just for people who create content on TikTok, but everyone who shares or views content,” said George Wang, a staff attorney at the Knight First Amendment Institute who helped write the institute’s amicus briefs on the case. 

“It sets a really dangerous precedent for how we regulate speech online,” Wang said.

Who supports and opposes the ban?

Dozens of high-profile amicus briefs from organizations, members of Congress and President-elect Donald Trump were filed supporting both the government and ByteDance.

The government, led by Attorney General Merrick Garland, alleges that until ByteDance divests TikTok, the app remains a “powerful tool for espionage” and a “potent weapon for covert influence operations.”

Trump’s brief did not voice support for either side, but it did ask the court to oppose banning the platform and allow him to find a political resolution that allows the service to continue while addressing national security concerns. 

The short-form video app played a notable role in both Trump and Democratic nominee Kamala Harris’ presidential campaigns in 2024, and it’s one of the most common news sources for younger voters.

In a September Truth Social post, Trump wrote in all caps Americans who want to save TikTok should vote for him. The post was quoted in his amicus brief.
