What is IPv4?

Example: 192.168.1.1

What is IPv6?

IPv6 is the successor of IPv4, designed to address its limitations. It uses 128-bit addresses and supports around 340 undecillion addresses.

Example: 2001:0db8:85a3:0000:0000:8a2e:0370:7334

Why the Shift to IPv6?

• ✅ Scalability: Enough IP addresses for every device imaginable
• ✅ Security: Built-in IPsec for encrypted communication
• ✅ Routing Efficiency: Better and faster routing mechanisms
• ✅ End-to-End Connectivity: No need for NAT

Current State of Cybersecurity Data Loss

Data Loss or Data Exfiltration

Data loss or data exfiltration is when data is intentionally or unintentionally lost, stolen, or leaked to the outside world. The data loss can result in:

• Brand damage and loss of reputation
• Loss of competitive advantage
• Loss of customers
• Loss of revenue
• Litigation/legal action resulting in fines and civil penalties
• Significant cost and effort to notify affected parties and recover from the breach

Network security professionals must protect the organization’s data. Various Data Loss Prevention (DLP) controls must be implemented which combine strategic, operational and tactical measures.

Data Loss Vectors

Data Loss Vectors	Description
Email/Social Networking	Intercepted email or IM messages could be captured and reveal confidential information.
Unencrypted Devices	If the data is not stored using an encryption algorithm, then the thief can retrieve valuable confidential data.
Cloud Storage Devices	Sensitive data can be lost if access to the cloud is compromised due to weak security settings.
Removable Media	One risk is that an employee could perform an unauthorized transfer of data to a USB drive. Another risk is that a USB drive containing valuable corporate data could be lost.
Hard Copy	Confidential data should be shredded when no longer required.
Improper Access Control	Passwords or weak passwords which have been compromised can provide a threat actor with easy access to corporate data.
