▪ A 2N5668 has VGS(off) = -4 v and IDSS = 5mA. What are gate voltage and drain

current at the half cutoff point?

▪ A 2N5459 has VGS(off) = -8 v and IDSS =

16mA. What is the drain current at the half

cutoff point?

A The term heuristics should be used where artificial intelligence (AI) is used to detect intrusions. IDSs that genuinely use heuristics have been allegedly almost ready for around a decade. It is my understanding that they still aren't quite clever enough and can be trained by an attacker to ignore malicious traffic. Some IDSs use anomalies to detect intrusions, where the IDS has to learn over time what can be considered normal. As this is fairly clever some vendors will sell this as a heuristic IDS. I can think of at least one IDS that does use an AI scripting language to apply analysis to the incoming data. Rather than learning what is normal signatures can be created that look for abnormal traffic these are sometimes referred to as heuristic signatures, ie., too many repeated characters in a URL.

From my experience, network security analysts should have the following character traits:

Honesty

Curiosity

Trustworthiness

Persistence - not easily discouraged

Humility, i.e. willingness to admit ignorance coupled with a commitment to find the answer

Discretion

In addition, a network security analyst should also have the following Non-character traits:

Intelligence

Extensive knowledge of computer security, especially the applicable laws, policies and procedures that apply to the network they are working with

Skill on methods for securing computers and computer networks

Skill in using network analysis tools such as Nessus, Snort, Netcat, Metasploit, Kismet, or tcpdump. There are lot of them, but a good analyst is skilled with enough of them to do his or her job well.

Understanding of the operating systems and applications in use on the network

Skill in database security if a DB is present on the system.

Skill in router and switch administration and security.

Skill in Intrusion Detection Systems (IDSs) and Intrusion Prevention Systems (IPSs)

Resources to identify people who have any skills that they lack - for example, if they don't have sufficient skills on routers and switches, they should be able to identify someone with those skills to team up with.

In a JFET with external bias, the transfer characteristics typically show how the output current (ID) varies with the input voltage (VG). By applying an external bias voltage between the gate and source terminals, the JFET operates in its active region, allowing for control over the output current. This biasing scheme enables fine-tuning of the JFET's operating point and can influence parameters like transconductance and overall performance.

Alliteration is the use of the same letters or sounds at the beginning of words that are near each other in a sentence. In the poem Palanquin Bearers, some examples of alliteration include "she sways", "she skims", "gaily we glide", and "like a laugh from the lips".
