Top challenges in cyber security

May 18, 2022, Learn eTutorial

In the present world, technology is advancing very fast, Individuals, organizations and even the government are depending on the internet and cyberspace for different activities that range from viewing a video to making a bank transfer. It is very difficult for many organizations, individuals, and government to protect their sensitive information and assets from cyber-attacks. Cyber security is doing that job for them to protect their data from cybercriminals. 

In the present situation, cyber security is playing one important role in safeguarding organizations and even a nation’s economic and sensitive information and devices. Nowadays there are a huge number of challenges are happening related to cyber security as the attackers are more efficient and many readily available tools are available on the internet. Each organization needs a cyber-security analyst to make sure they are protected. 

Cyber security challenges are in different forms and ways like Ransomware, Malware attacks, Phishing attacks, and many more that may even affect a country’s economic conditions. In these cyber security tutorials, we are going to know about 10 top cyber security challenges.

  1. Ransomware attacks
  2. IoT attacks
  3. Cloud attacks
  4. Phishing attacks
  5. Blockchain & cryptocurrency attacks
  6. Software vulnerabilities
  7. Machine learning and Artificial intelligence attacks
  8. Insider attacks

Ransomware attacks

Ransomware attacks are one of the modern cyber-attacks that almost all organizations around the globe are facing. According to the data, around 60 to 70 percent of IT and related institutions are the victims of ransomware attacks. 

Ransomware is a kind of malware that attacks a system and lock the system and its data. Hackers behind the ransomware will ask for a ransom and they release the lock only if they are paid. Some of the hackers never release the system even after the payment is made as they ask for more payments. 

The infected system is locked and all the data inside the system cant be accessed until the payment is made. It makes a huge loss for IT companies and financial institutions if the data is lost. Ransomware attacks are increasing day by day

In the present condition, the DRaaS solution is the best strategy to secure ransomware. In this method, we should take a backup automatically at regular intervals and once the system is infected we have to restore the clean version of the backup and use the system.

IoT Attacks

IoT is the short form for the Internet of Things; It is the most modern revolution in the technology world, as it is a system of so many devices that are interconnected through the internet and works using the internet for data transfer. IoT devices are working with the help of a UID number and it can transfer data using that UID. The operating system and the software, which is used in the IoT devices, are susceptible to a cyber-attack making a window for attackers to access the sensitive information.

According to the latest data around 20 billion IoT devices are connected through the internet in 2022 and it is increasing at a high rate. Protecting these devices is challenging for a cyber-security team and it must be protected to safeguard the sensitive information inside these devices. Every organization must have a cyber-security team to make security for passwords, session handling, user verification, multi-factor authentication, etc.

Cloud Attacks

Cloud storage services are an upcoming trend in storage. Most individuals and organizations are using cloud services for storage and access. This upward trend in the usage of cloud storage and services makes cybercriminals focus on the cloud. 

We all have heard about an attack on cloud storage called the I-cloud hack which exposed the photos of many celebrities and famous people. In the current scenario data stealing from the cloud is one of the big challenges in cyber security. 

Once the cloud security is compromised, it will make a disaster like a huge amount of sensitive information are now in cloud storage. This can make organizations, even governments fall. 

Phishing and Spear-Phishing Attacks

Phishing attacks are common attacks that cybercriminals use to gain information from the victims about their bank details, credit card details, and other sensitive information. In a phishing attack, the hackers will use websites or emails that may look legitimate but contain malicious code that will take your details to the hacker’s database. 

How phishing attacks are different from ransomware is both are taking the user's sensitive information but in phishing attacks, the hacker will not lock the victim's data but rather use that sensitive information for illegal activities like stealing money from their account, etc until the victim knows about it and take necessary countermeasures.

In the case of spear phishing, cybercriminals use emails and other messages targeted at specific victims. In this case, the hackers will study their victims and their interests and make the trap according to that like malicious emails or messages.

As millions of new users are using the bank's online services and the internet without proper knowledge and precautions, phishing attacks and spear-phishing attacks are becoming one of the main challenges in cyber security.

Blockchain and Cryptocurrency revolution

Blockchain is one of the latest technology revolutions that laid the building base of cryptocurrencies like Bitcoin, Etherium, etc. Blockchain technology is offering a digital medium for transactions without a third party that we call peer-to-peer transactions. As we know the blockchain is a global platform that makes the concept of Bitcoin which can make transactions without a third party like financial institutions. 

It is difficult to predict the security of the blockchain. It is not clear what level of security this technology is offering. Different cyber security experts are predicting that it offers worthy security and it has passed the infancy stage but not cleared its advanced security stage. 

Making this technology secure is one of the challenges of cyber security in these times as some DDOS attacks, Sybil, and Eclipse attacks are targeted such as blockchain and cryptocurrencies.

Machine Learning and AI revolution

Machine learning and Artificial intelligence are booming a lot. John McCarthy who is known as the father of AI stated that Artificial intelligence is a combination of science and engineering that make intelligent machines. 

Machine learning and AI has huge application-level opportunities that include problem-solving, pattern recognition, take intelligent decisions, etc, even these technology is highly used in cyber security to analyze the threat from the huge amount of data and take the necessary steps. 

Even the AI and ML are doing a great job, it is also vulnerable to cyber-attacks from professional-level cyber attackers. This technology is taking the decisions depending on the huge data set; any manipulation in the dataset will make dangerous decisions from the AI. So it is again a challenge for cyber security.

Software and Apps Vulnerabilities

We are all using software and apps for different activities in our systems and in mobile devices. Even if this software is perfect and secure, there must have some vulnerabilities inside it, which can make the hackers penetrate into, the software can steal the data. 

Usually, organizations and individuals are not making their software up to date because of ignorance, and some use illegal versions. It may cause negative results as this software has patches and vulnerabilities and the developers remove such things in the update. So every software must be up to date. 

Using software and apps without much concern is one of the challenges in cyber security at the current time. 

Insider attacks

Till now we have discussed the challenges for cyber security professionals which are coming from external sources and he has to protect the organization from them. In some cases, the employees who have illegal interests will try to attack the organization from the inside. It will be leaking sensitive data or making some important machines nonfunctional.

This type of inside challenge also has to take care of by cyber security by using a firewall for monitoring both inside and outside traffic. Limiting the access to the employees to only their department and additional access will be allowed only if it is necessary.
