A. Copy and Paste Naturally, you can copy frames and their content, together or separately, from within InDesign and paste elsewhere within InDesign. You can copy type from the middle of a story and paste it, too. I won’t waste your time talking about something as academic as that. I would like to spend a few paragraphs discussing what can and can’t be copied into InDesign from other applications and some of the things to watch out for when doing that. InDesign’s drawing tools are perfect for most common drawing tasks. When you need something a little more robust, however, haul out Illustrator. When you do that, you have a choice: Save the Illustrator file and place it into InDesign as an asset, or simply copy the artwork from Illustrator and paste into InDesign. Both methods works, and each has its pros and cons. InDesign understands vector paths and basic shapes about as well as Illustrator, and, more importantly, InDesign is wise enough to recognize when something—in this c...

1.1.1 Types Of Detection 1.1.1.1 Signature Detection Protecting the network against known attacks. Attackers often attack networks through tried and tested techniques from previously successful methods. These threats have been analyzed by network security engineers and a listed profile, or specific signature has been created. Signature detection methods examine network by looking for the threat’s fingerprint inside the network traffic and matching against an internal database of known attacks. Once an attack signature is determined, the security device delivers an attack response, mostly in a form of simple alarm or alert. Success in preventing these threats depends on the minute database of attack signatures, compiled from previous records. The drawback to systems on signature detection is clear: they can only detect threats for which there is a defined signature. If signature detection methods are employed to protect networks, the network is protected against known attacks on...

Ten Security Tips 1. Require or encourage workers to choose passwords that are difficult to judge. 2. Workers should change passwords every three months. 3. Make sure your virus protection subscription up to date. 4. Educate workers about the security risks of electronic mail attachments. 5. Implement a comprehensive and complete network security solution. 6. Assess your security regularly. 7. When a worker leaves a company, remove immediately that employee’s network access. 8. If you allow employees to work from home then provide a secure server for remote traffic. 9. Make sure that your Web server software is up to date. 10. It is no recommended that you run unnecessary network services.

1.1 Types of IDS/IPS The following are the types of IDS/IPS 1.1.1 Network Based It performs packet sniffing and evaluates network traffic to recognize and prevent from suspicious activity. They are typically placed inline mode as a network firewall. They receive packets, examine them, decide if they should be permitted, and allow satisfactory packets to pass through. Figure 2- 3 Network based IPS 1.1.2 Host-based It is similar to network-based , apart from that a host-based product senses the characteristics of a single host and the events occurring within that host, similar to sensing network traffic (only for that specific host), system logs, running processes, file access and modification etc.
