Online Threats and How to Safeguard Against Them

Online Threats pose substantial threats to people and their computer systems, such as malware, phishing attempts, and other forms of cybercrime. These types of threats aim to disrupt and destroy digital assets such as networks, computers, and data. They also have the potential to steal personal information and extort money from individuals and businesses alike.

Online Threats and How to Safeguard Against Them


Network Detection and Response (NDR) is a critical cybersecurity solution that scans network traffic to detect suspicious connections and block them if necessary. NDR uses machine learning techniques along with behavioral analytics to interpret raw network data.

NDR products employ these techniques to construct models of expected network behavior. They then compare suspicious traffic against this baseline, flagging any activity that deviates from the expected pattern. When this occurs, the system alerts network security teams.

An effective NDR tool can detect suspicious behavior that would have gone undetected by traditional signature-based tools. This may include insider attacks or risky practices like sharing user accounts, giving unauthorized users access to confidential data, and granting remote access to endpoints.

Additionally, NDR solutions possess the capacity to decrypt encrypted traffic in order to provide complete visibility into malicious activity. This is essential as over 90% of malware resides within encrypted channels; conventional firewalls and EDR tools lack this capability, leaving them blind to threats that might otherwise go undetected.

Additionally, NDR systems employ secure data collection methods that cannot be altered; making them ideal for digital forensics and other compliance demands. NDR solutions can even correlate multiple sources to determine how an attacker entered a network and spread laterally throughout it.

They can be an invaluable asset for mitigating the effects of cyber-attacks on your organization, enabling you to act swiftly and efficiently. This helps avoid major losses caused by malicious behavior such as costly ransom payments, data loss, or business disruption.

NDR is an integral element of any comprehensive cyber security strategy, capable of detecting and containing sophisticated, advanced threats. It serves as the last line of defense against cybercriminals and offers a comprehensive view of the attack cycle. When used together with other security tools, NDR detects and blocks attacks from infiltrators before they cause property damage or disrupt business operations.

Network Firewall

Network firewalls are an essential security measure to shield business networks from online threats. They allow and reject network traffic according to predefined security rules, which can either be manually entered or automated and range from simply allowing or blocking to stateful inspection.

Firewalls offer a number of other advantages, such as web filtering and spam/phishing protection. Furthermore, firewalls protect an organization against ransomware attacks and other malware attacks.

Network firewalls are composed of hardware and software that allows the user to create and enforce security policies. Depending on the type, this device could be either a stand-alone appliance, or it could be hosted directly on your computer.

In most cases, a firewall stands between an internal network and the public internet. This could either be an internet connection or even something private like your home network.

Some firewalls can also be utilized within a home network to enforce restrictions between devices. When combined with antivirus applications, these guard against malicious software that has been installed on a device.

These types of firewalls use packet filters to inspect data sent between computers. They can permit or deny packets based on their source IP address and ports.

However, these filters do not inspect the content of each packet, making them ineffective against determined attackers who know exactly what they're doing and are ready to launch their own attacks against the firewall on their own.

Another type of firewall is a circuit-level gateway, which permits packet inspection at the surface by inspecting the Transmission Control Protocol (TCP) header. Based on what rules you have configured in advance, the firewall will determine whether a packet should be allowed or denied based on these pass/fail rules.

This type of firewall can prevent a web server from establishing a connection with a client by inspecting the request and sending it to a proxy*, which then connects them. This enables the firewall to inspect each packet's payload in order to differentiate malicious code disguised as valid requests for data.

Endpoint Protection

Endpoint Protection provides IT organizations with the means to defend their devices against malware, ransomware, and other threats. It also guards against data breaches which could result in costly business losses, regulatory fines, and damage to trade secrets.

Cybercriminals employ a range of tactics to breach networks and steal private information, such as social engineering and phishing. They target organizations of all sizes - from small offices to multinational corporations - with these attacks costing businesses tens of millions in damages due to forensic investigation, remediation costs, and ransomware payments.

Unfortunately, traditional antivirus software cannot keep up with the evolving threats. Hackers and cybercriminals have become more adept at breaching security systems, necessitating endpoint security solutions to be more layered and sophisticated than ever before in order to remain effective.

Modern endpoint protection increasingly relies on machine learning to learn how to recognize new malware. This technique allows it to automatically classify threats in real time based on the behavior of the files being analyzed.

One advantage of this approach is that it's simpler to implement and manage than traditional security platforms, which often rely on users manually updating software. Furthermore, IT pros can monitor all endpoints' health from a centralized console.

Another advantage of a cloud-based solution is its hybrid capability, enabling companies to run in both on-premises and cloud environments simultaneously. This provides greater adaptability and scalability while still providing security against today's most sophisticated threats.

A successful endpoint security strategy utilizes multiple layers of defense to help organizations anticipate threats, gain visibility into devices and simplify management. It also assists organizations in fulfilling data security regulations that require them to safeguard sensitive business data as well as guarantee employee productivity.

In addition to anti-malware or antivirus, endpoint protection software also encrypts data and applications on endpoints, blocks access to certain file types and folders, detects sensitive data, and enforces enterprise classification, as well as prevents employees from circumventing security policies. These capabilities can save a company a considerable amount of money over time by avoiding expensive remediation expenses, safeguarding trade secrets and other intellectual property, as well as preventing data leaks.

Malware Protection

Malware, or malicious software, is an umbrella term for various programs designed to cause computer system damage. These could include viruses, worms, trojans, and ransomware. Not only can these corrupt or steal personal information but they may also demand money from users in exchange for data restoration services.

These threats are becoming increasingly sophisticated, so malware protection should be an integral part of your overall security plan. Adopting a layered approach will provide more opportunities to detect, mitigate and eliminate malicious software before it causes real harm.

Many malware attacks are carried out through social engineering techniques, such as phishing scams that target individuals with fraudulent emails containing links to infected websites or malicious attachments. These attempts are designed to trick victims into downloading or opening the malware. Other ways of delivering it onto computers include drive-by downloads - which automatically install a virus without user interaction on compromised websites - and exploits of vulnerabilities in software and communication protocols.

Other types of malware include spyware, which monitors users' activities and sends the data it collects to attackers. It may also steal financial credentials and transfer funds without authorization. Lastly, ransomware encrypts files so they cannot be restored unless a ransom is paid.

Spyware can collect information on network traffic, such as the sites and services users access. It has the potential to eavesdrop on internet conversations through webcams or microphones.

Viruses and worms are the two most widespread forms of malware, although spyware and Trojans may also infect computers. Viruses and worms have the ability to damage files, corrupt operating systems, and deliver a payload at a predetermined time; similarly, worms spread silently from one infected computer to other devices without the human interaction required.

Some types of malware employ a command-and-control server, enabling attackers to communicate with infected devices and exfiltrate data. This capability could enable cyberattacks against larger targets as well as disrupt network infrastructure.

To protect against malware, the best approach is to practice good cyber hygiene. This includes keeping your system up to date with security patches and ensuring your employees understand online safety basics and use strong passwords. Furthermore, continuous authentication and limiting access to critical systems and data on a need-to-know basis can help safeguard your business.

You Need More Than Software

The last thing we have to highlight is that the biggest threats for computers and businesses is not the actual software utilized to attack. It is the user. This is why, especially for a company, you have to train your employees to be aware of the countless threats that are coming their ways. Investing in an education program is the best thing you could do.

Online Threat Alerts Security Tips

Pay the safest way

Credit cards are the safest way to pay for online purchases because you can dispute the charges if you never get the goods or services or if the offer was misrepresented. Federal law limits your liability to $50 if someone makes unauthorized charges to your account, and most credit card issuers will remove them completely if you report the problem promptly.

Guard your personal information

In any transaction you conduct, make sure to check with your state or local consumer protection agency and the Better Business Bureau (BBB) to see if the seller, charity, company, or organization is credible. Be especially wary if the entity is unfamiliar to you. Always call the number found on a website’s contact information to make sure the number legitimately belongs to the entity you are dealing with.

Be careful of the information you share

Never give out your codes, passwords or personal information, unless you are sure of who you're dealing with

Know who you’re dealing with

Crooks pretending to be from companies you do business with may call or send an email, claiming they need to verify your personal information. Don’t provide your credit card or bank account number unless you are actually paying for something and know who you are sending payment to. Your social security number should not be necessary unless you are applying for credit. Be especially suspicious if someone claiming to be from a company with whom you have an account asks for information that the business already has.

Check your accounts

Regularly check your account transactions and report any suspicious or unauthorised transactions.

Don’t believe promises of easy money

If someone claims that you can earn money with little or no work, get a loan or credit card even if you have bad credit, or make money on an investment with little or no risk, it’s probably a scam. Oftentimes, offers that seem too good to be true, actually are too good to be true.

Do not open email from people you don’t know

If you are unsure whether an email you received is legitimate, try contacting the sender directly via other means. Do not click on any links in an email unless you are sure it is safe.

Think before you click

If an email or text message looks suspicious, don’t open any attachments or click on the links.

Verify urgent requests or unsolicited emails, messages or phone calls before you respond

If you receive a message or a phone call asking for immediate action and don't know the sender, it could be a phishing message.

Be careful with links and new website addresses

Malicious website addresses may appear almost identical to legitimate sites. Scammers often use a slight variation in spelling or logo to lure you. Malicious links can also come from friends whose email has unknowingly been compromised, so be careful.

Secure your personal information

Before providing any personal information, such as your date of birth, Social Security number, account numbers, and passwords, be sure the website is secure.

Stay informed on the latest cyber threats

Keep yourself up to date on current scams by visiting this website daily.

Use Strong Passwords

Strong passwords are critical to online security.

Keep your software up to date and maintain preventative software programs

Keep all of your software applications up to date on your computers and mobile devices. Install software that provides antivirus, firewall, and email filter services.

Update the operating systems on your electronic devices

Make sure your operating systems (OSs) and applications are up to date on all of your electronic devices. Older and unpatched versions of OSs and software are the target of many hacks. Read the CISA security tip on Understanding Patches and Software Updates for more information.

What if You Got Scammed?

Stop Contact With The Scammer

Hang up the phone. Do not reply to emails, messages, or letters that the scammer sends. Do not make any more payments to the scammer. Beware of additional scammers who may contact you claiming they can help you get your lost money back.

Secure Your Finances

  • Report potentially compromised bank account, credit or debit card information to your financial institution(s) immediately. They may be able to cancel or reverse fraudulent transactions.
  • Notify the three major credit bureaus. They can add a fraud alert to warn potential credit grantors that you may be a victim of identity theft. You may also want to consider placing a free security freeze on your credit report. Doing so prevents lenders and others from accessing your credit report entirely, which will prevent them from extending credit:

Check Your Computer

If your computer was accessed or otherwise affected by a scam, check to make sure that your anti-virus is up-to-date and running and that your system is free of malware and keylogging software. You may also need to seek the help of a computer repair company. Consider utilizing the Better Business Bureau’s website to find a reputable company.

Change Your Account Passwords

Update your bank, credit card, social media, and email account passwords to try to limit further unauthorized access. Make sure to choose strong passwords when changing account passwords.

Report The Scam

Reporting helps protect others. While agencies can’t always track down perpetrators of crimes against scammers, they can utilize the information gathered to record patterns of abuse which may lead to action being taken against a company or industry.

Report your issue to the following agencies based on the nature of the scam:

  • Local Law Enforcement: Consumers are encouraged to report scams to their local police department or sheriff’s office, especially if you lost money or property or had your identity compromised.
  • Federal Trade Commission: Contact the Federal Trade Commission (FTC) at 1-877-FTC-HELP (1-877-382-4357) or use the Online Complaint Assistant to report various types of fraud, including counterfeit checks, lottery or sweepstakes scams, and more.
  • If someone is using your personal information, like your Social Security, credit card, or bank account number, to open new accounts, make purchases, or get a tax refund, report it at This federal government site will also help you create your Identity Theft Report and a personal recovery plan based on your situation. Questions can be directed to 877-ID THEFT.

How To Recognize a Phishing Scam

Scammers use email or text messages to try to steal your passwords, account numbers, or Social Security numbers. If they get that information, they could get access to your email, bank, or other accounts. Or they could sell your information to other scammers. Scammers launch thousands of phishing attacks like these every day — and they’re often successful.

Scammers often update their tactics to keep up with the latest news or trends, but here are some common tactics used in phishing emails or text messages:

Phishing emails and text messages often tell a story to trick you into clicking on a link or opening an attachment. You might get an unexpected email or text message that looks like it’s from a company you know or trust, like a bank or a credit card or utility company. Or maybe it’s from an online payment website or app. The message could be from a scammer, who might

  • say they’ve noticed some suspicious activity or log-in attempts — they haven’t
  • claim there’s a problem with your account or your payment information — there isn’t
  • say you need to confirm some personal or financial information — you don’t
  • include an invoice you don’t recognize — it’s fake
  • want you to click on a link to make a payment — but the link has malware
  • say you’re eligible to register for a government refund — it’s a scam
  • offer a coupon for free stuff — it’s not real
