Viruses	Loss of data, downtime
Worms	Network outages, data destruction
Ransomware	Data loss, ransom payments
Spyware	Data theft, surveillance
Botnets	DDoS attacks, malware distribution
Rootkits	Full system compromise
Keyloggers	Credential theft, fraud

Protecting Against Malware

Defending against rapidly evolving malware requires a layered approach:

• Keep all software up-to-date with the latest security patches
• Use antivirus/antimalware tools on endpoints and networks
• Be vigilant against suspicious emails, links, and attachments
• Train employees to identify social engineering techniques
• Segment networks to limit the spread of infections
• Backup critical data regularly in case of malware encrypting files
• Use next-gen tools like EDR to detect and block advanced threats

Staying on top of new malware developments and taking proactive measures to harden infrastructure is key to avoiding business disruption. Partnering with cybersecurity experts can provide resources and technology to combat modern malware threats.

The Threat of Data Breaches

Data breaches pose a major risk for any business that collects sensitive customer, employee, or business data. Unfortunately, data breaches are increasingly common, with the average cost of a breach reaching $4.35 million in 2021. Understanding potential causes of data breaches and implementing preventative measures is key to avoiding this expensive and reputation-damaging threat.

How Data Breaches Happen

• External attacks – Hackers exploit network vulnerabilities, endpoints, or cloud apps to steal data. Phishing emails are a common entry point.
• Malware – Malicious software like trojans or ransomware infiltrates systems to expose data.
• Insider threats – Employees, contractors, or partners abuse access to exfiltrate confidential data.
• Third-party risks – Vendors, suppliers, or other business partners suffer breaches compromising your data.
• Human error – Employees misconfigure systems or accidentally post data publicly.

Breach Source	Business Impact
External attacks	Theft of customer/employee PII, credentials, intellectual property
Malware	Encryption of sensitive data, extortion
Insider threats	Loss of trade secrets, intellectual property
Third parties	Supply chain disruption, loss of customer trust
Human error	Public exposure, compliance violations

Securing Your Data

• Employ in-depth defense with firewalls, endpoint security, access controls, encryption, and intrusion detection.
• Prioritize patching known system vulnerabilities that can be exploited.
• Implement policies like least-privilege access and separation of duties.
• Train staff on secure practices like strong passwords and phishing avoidance.
• Vet third parties’ security measures if they handle your data.
• Backup critical data regularly in case of destructive attacks.
• Have an incident response plan ready in case a breach occurs.

A layered approach to security and keeping data protection at the forefront can help mitigate this threat. Partnering with cybersecurity experts provides extra resources and technology to lock down your data.

Defending Against Phishing and Social Engineering

Phishing and social engineering attacks aim to manipulate users into handing over sensitive data or access. These attacks commonly rely on crafted emails, websites, phone calls, or even social media to impersonate trusted sources. Businesses must train staff to identify and avoid these schemes.

Phishing Tactics

• Spear phishing – Targets specific individuals with personalized messages to appear more legitimate.
• Whaling – Aim at high-profile targets like executives to access financial systems or data.
• Vishing – Uses phone calls or voice messages to extract information by impersonating vendors or IT teams.
• Business email compromise (BEC) – Spoofs executive emails to request fraudulent wire transfers.
• Malicious links – Fake login pages to steal credentials or downloads infected with malware.

Social Engineering Techniques

• Pretexting – Inventing a scenario to trick the victim into sharing info.
• Baiting – Offering free downloads like movies with malware attached.
• Quid pro quo – Offering a service in exchange for login or bank account access.
• Tailgating – Following an employee into a secure building without authorization.

Protection Tips

• Enable email filtering tools to block suspected phishing content.
• Teach employees how to identify phishing URLs and impersonation attempts.
• Require callbacks for any payment or data transfer requests by phone or email.
• Limit data access to only necessary employees to reduce insider misuse.
• Use security awareness training, including simulated phishing attacks.

With the right preparation, staff can become an organization’s best defense against these threats. Partnering with cybersecurity experts provides extra training resources and technology to thwart phishing and social engineering schemes.

Defending Against Network Attacks

While endpoints like laptops and servers are common targets, attackers also exploit vulnerabilities in network infrastructure and protocols for access and disruption. Businesses should understand common network-focused attacks to secure critical systems properly.

Network Attack Types

• DDoS – Floods networks with junk traffic to overwhelm and shut down websites or web apps.
• DNS tunneling – Encodes data in DNS queries to create covert channels for data exfiltration or command and control.
• MITM attacks – Intercepts unencrypted traffic between systems by spoofing each endpoint. Allows data theft or injection of malicious payloads.
• Sniffing – Uses packet capture tools to intercept transmitted data, including unencrypted passwords or emails.
• Spoofing – Forges source IP addresses, domain names, or email headers to impersonate trusted entities.

Key Protections

• Use firewalls and web application firewalls to filter malicious traffic and payloads.
• Encrypt network traffic and implement VPNs to prevent sniffing and MITM attacks.
• Harden network devices against common exploits using patching and access controls.
• Monitor traffic patterns to detect DDoS spikes or abnormal DNS queries.
• Implement redundancy and load balancing to maintain availability during DDoS.
• Use tools like intrusion detection systems to identify malicious network activity.

Securing this critical layer is essential, with networks forming the backbone of modern business. Partnering with cybersecurity experts provides the technology and skills to lock down networks against attacks.

Addressing Vulnerabilities for Security

Along with external threats, vulnerabilities in an organization’s systems and processes open the door to many cybersecurity risks. Unpatched software, weak passwords, and misconfigured systems are common issues that allow attackers access.
