What is the routine procedure for quarantining?

Should you quarantine every new Koi that you buy, even if they’ve been quarantined at the dealer first? 

Ian Wellby says...

The purpose of quarantine is to establish whether the new fish has a disease, which could adversely affect the resident fish. Any diseases that do show up can then be more easily treated in a quarantine system and will not spread to the resident population. It also gets the fish used to the conditions prevalent in your area. The fish should be kept in quarantine for at least two weeks and up to three months, preferably including some of the warmer spring and summer months. If this is not possible, heat the quarantine tank for a period up to 20˚C and then let it settle back to ambient temperature. This will help bring out any diseases that might be present. Every fish you put into your pond must be quarantined. The quarantine system should be large enough and have suitable filtration. If possible it should initially be filled with water from the pond and any water changes should be completed using pond water. All equipment (nets and buckets) should only be used within the quarantine system; colour code them with yellow electrical tape so there are no mistakes. Finally, it is a good idea to quarantine new fish with resident fish. If one or two resident fish are put in the quarantine system, not only will they keep the filters ticking over, but they will also react quickly to any nasty disease that the new fish have brought in. The quarantine the fish undergo at the dealer’s premises will not match your requirements, but it is good practice on the part of the dealer.

When ever I buy new koi .I aleays place it in isolation for the purpose to check.If there is any disease present in it then I never include it with other resident fishes.Recently I got high speed internet service for the purpose to search about different types of Koi.I want to purchase koi from england.I had found lot of beautiful and interesting kois online but I am afraid to purchase online due to difficult and risky credit card processing methods.I am a whole saller of koi and import large quantity of kois from srilanka and bangaladesh and I place order by using land line phone now I got idea of internet phone service which is very cheap as well as money is concerned.

 
 

Quarantining Process used by IT Staff Members

Introduction

Quarantining is the process of isolating or removing a system from Rice’s network. Systems are quarantined based on observed threats to other systems via online payment (Rice and/or non-Rice) or by direction from University officials (President’s Office, General Counsel’s Office, Rice Police Department, Human Resources, etc). All requests from non-Rice law enforcement agencies should go through the General Counsel’s Office.

Threats

Threat Observation

Threats are observed through passive scanning sensors on the network and reports from other Rice and non-Rice users and groups.

The sensors identify potential threats based on the observation of sudden, unexpected spikes in anomalous traffic from one or more hosts and traffic signatures matched to a known threat.

Other users and groups on campus also have systems that detect such traffic and report anomalies to the IT Security Office. The IT Security Office responds to these reports on wireless internet after the anomalies are verified.

Threat Level Determination

The threat level is determined by the nature and severity of the observed traffic. If a system is observed in what appears to be an attack against multiple Rice and/or non-Rice systems, it is classified as a high-risk threat. If a system is simply observed with traffic with a known malicious signature, such as a virus infection, the system is classified as a low-risk threat.

Quarantine

Quarantine as Directed from University Officials

In rare circumstances, University officials may request that a system be quarantined or removed from the network. In each case, timeline and notification parameters will be determined by collaboration between the requestor and the IT Security Office.

Quarantine due to High-Risk Threats

Systems that are determined to be a high-risk threat are either immediately quarantined or otherwise removed from the network. The IT Security Office will notify the IT Support Provider and/or the Primary User as soon as they are identified.

Quarantine due to Low-Risk Threats

Systems that present a low-risk threat will be quarantined after an attempt is made to contact the IT Support Provider or Primary User of the system. The IT Security Office will allow three hours between attempted contact with the IT Support Provider/Primary User and the quarantine or removal from the network. If a contact for the dsl system cannot be identified, the help desk will be notified instead.

Exceptions
 

  • The systems are providing critical services, such as multi-user servers and workstations.
  • If possible, steps will be taken to keep critical services online while either containing or eliminating the malicious process(es) until the system can be taken down and remedied with less user impact.
  • Also, the IT Security Office will attempt to notify before the system is removed from the network; however, if a contact cannot be identified or a response has not otherwise been received, the system will be either quarantined or removed from the network immediately for high-risk threats and after three hours for low-risk threats.
  • The IT Security Office determines that the system should stay online as part of an investigation.
  • The IT Security Office is directed by a University official to keep a system online despite a threat.
  • Remediation

Examples

Example 1: SSH Scan

A system on the Rice network is detected actively scanning other Rice systems on tcp port 22, trying to log on repeatedly with multiple usernames and passwords faster than a person could do so.

Example 2: DMCA

The General Counsel’s office receives official contact from a copyright holder that a Rice system has infringed upon that copyright by the unauthorized sharing of a movie in Divx format.

a thorough studdy instead

this is definitely a thorough study and the process decribed here surely need a lot of research on the perticular topic. great work done by............
