Risk & Security vulnerability for using default ports

Dear All,
As far as I know, Oracle does not recommend to use default ports for
security purposes. Searching out of Oracle community found that some people
think that it does not matter any more. However, it can have some vulnerability
and, I think, security risk & auditors would not like to see that.
I have found that in 2012 ORacle Tns listener port 1521 had a vulnerability
issue with oracle database 11gR1 and 11gR2, but how about Oracle 12?.
Also, I was searching something similiar for Oracle OAM, SOA, OIM, OAAM, but still cannot
find anything.
Thanks

Do you happen to have such a storage peripheral attached to your M3000?
If yes, then it is probably reachable through the M3000's IP address. You will need to log a support ticket with HP and get guidance how to get into the array's FCAL controller and investigate the issue.
If you do not have an HP array attached to your M3000, then log a support case with Oracle and arrange for a field service engineer to visit the site to manipulate the password for its `admin` account (since that special account is likely needs service-employee-only access).
Either way, you need to get accurate technical support and this forum is NOT official tech-support.

Is there any internet security needed for use with the ipad 2??

is there any internet security needed for the ipad 2? I.e. For when you're shopping online etc?

You don't have to purchase a mouse. You already have one, it's wireless and the only one that will work on an iPad.

O make the In system preferences under Sound, there is no drop-down menu for "Use audio port for." How do I switch the port to input?

I'm trying to use the audio input/output port to record in Garageband. When I plug in my guitar it isn't recognized, and when I go to sound prefrences it does not give me the option to switch between input and output. How do I switch it to input?

For GarageBand issues post in that forum.

How can I view and convert .264 files from my security cameras for use on my Mac and the web?

My security cams record in a .264 file format HD. I want to view, edit, etc on my Mac, what software will do that and are there any easy tips to do this? I'm new to Mac's so I'm not sure what is the best format to convert to? mp4? Suggestions?
Thanks in advance. I do love the Mac so far.

I have downloaded the trail....and it won't recognize my .264 files....not sure what the deal is? Here is a screen shot-they files are "grayed" out....and won't highlight. Do you see anything wrong? I'm pulling the files off of a Lorex DVR security system. LHD200

Wireless webcam / security cam for use with Intel iMac

Hi all. I want to set up an outdoor web/security cam and a wireless model would be ideal, as I want to be able to put it in different locations.
There seem to be many PC-compatible wireless cameras, but are there any which are compatible with the Mac OS? I don't really want to get into Boot Camp / Parallels territory if possible.

TNS-12541 : Why use default port 1521 ?

Hi,
I just upgraded my base from 10.2.0.5 to 11.2.0.2.
I followed all steps from the SAP Marketplace : Upgrade to Oracle Database 11g Release 2 (11.2): UNIX
My database is upgraded and I need to perform post-upgrade tasks before updating my Client.
When I try to execute tnsping, i got this error :
Attempting to contact (DESCRIPTION=(CONNECT_DATA=(SERVICE_NAME=))(ADDRESS=(PROTOCOL=TCP)(HOST=10.66.XX.XX)(PORT=1521)))
TNS-12541: TNS:no listener
I can't understand why he's trying to contact port 1521 while my tnsnames and listener.ora are :

So why contact port 1521 insted of 1527 ? Did I forget a file to modify ?

Securing ipad for use in public

I want to donate the use of our ipad1 to a small thrift store which I help to run. I need a way to ensure that no one walks off with it. Any good ideas?

You could try something similar to this:
http://www.anchorpad.com/products/plate-systems/ipad-plate-system
Basically encases it in a metal shield which is then anchored to a table or other such location. Not sure how you intend to use the iPad, whether you need it to be mobile or what not, but this is merely one solution.

IdM doesn't support non-default port on mysql 4.1 as repository??

Hi
IdM doesn't support non-default port on mysql 4.1 as repository??
IdM version is 6.0.
I setup mysql 4.1 using non-default port 3307.
(default port is 3306)
During setup wizard,
the URL [jdbc:mysql://localhost:3307/waveset] doesn't work.
I am getting following error.
com.waveset.util.InternalError:
==> com.waveset.util.ConfigurationError:
==> com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception:
Of cource,
the URL [jdbc:mysql://localhost/waveset] works well
when I setup mysql using default port.

Hi,
it does work with non standard ports but whatever port you specify it will always try to connect to the default port before actually changing the repo setting.
Therefore use the switches -n -o $WSHOME/WEB-INF/ServerRepository.xml to write the new configuration without performing the broken checks.

Using defaults to remove a dock icon...

I've been tinkering with this for a full day now and haven't really gotten out of the starting gate.
Does anybody have a working example for using 'defaults' to delete anything...
And yes I know defaults is run from a shell and this is technically not an AS related question, but it can be called from AS, so I'm asking.

Using defaults for arrays and records is pretty much a mess - is there a particular reason for not wanting to use the System Events *Property List Suite* or a scripting addition such as the Satimage XMLLib osax?
Note that the Dock preferences property list only keeps track of the applications and other items that you are keeping there (minus the FInder), and to update you will need to restart the Dock. Just dragging the item off the Dock sure seems simpler to me.

RBHi RB ,
22 is default port for ssh. For configuring

For non default port , first of all you need to configure ssh on new port . For that refer :

Default security context for signed applets using WinXP+IE8

What is the default security context for signed applets from the internet zone using Java 6 and WinXP+IE8 combination? My guess is that all file and socket access available for the user's Windows account is provided to the applet as well. Is this correct and if so, is there a way to limit these access privileges for signed applets from the internet zone?
This information is surprisingly difficult to find given how security concious people now are using the internet.

AntonBoer wrote:
Thank you for your swift reply.
Unfortunately your answer reflects to my worst fears. Frankly I find this security model naiive. Anyone with euros can get their applet signed so that is no security control at all.The same naive security model applies to just about anything signed and downloaded; not just to Java Applets.

Working for a corporate IT how I am supposed to allow Java installations on any of our computers with internet access? That automatically means I am providing them as platforms to whoever wishes to run Java code on them (given that the user of course visits the web site). I would have expected Sun to put more effort into this but it appers nothig have changed in this regard for 10 years.I don't see this as a Sun problem; it is indicative of what I consider to be a general security weakness for all computer systems. For example, for Windows, Vista just added more user involvement in the trust process but it still allows programs to run pretty much unconstrained if the user agrees to them running.
For some time I have advocated a more fine grained approach. I would like to see ALL programs run in a sandbox that a user can specify what and what cannot be done by each individual program. Unfortunately, this would annoy the hell out of most users so it has little chance of every of ever being accepted. The average user just wants a run-and-forget-about-security model.

I'm using my iPad with iOS v 6.1.3- is there a security patch for the SSL/TLS vulnerability for this, or do I have to go to 7.0.6?

I'm using my iPad with iOS 6.1.3. Is there a security patch for this version, or do I have to update to iOS 7.0.6?

There is an update for iOS 6... v6.1.6. But it is only available to iPhone 3GS and iPod touch 4th gen users. http://support.apple.com/kb/HT6146?viewlocale=en_US&locale=en_US
For iPad, the highest supported os for iOS 6 is v6.1.3. If you want to get the security patch, you'll have to go to iOS 7.0.6.
Hope this answers your question.

Change default port used for FlexUnit reports

Good day,
I have recently set up a CruiseControl server that runs two concurrent builds. Most of these builds contain FlexUnit tests. I am well aware that the default port for FlexUnit task is 1024 and I know that only one listener can access the port at one time. I tried passing a different port number but the flexunit task hangs. So, I was wondering if anyone has tried changing the default port to something other than 1024.

Hi Michael,
I created a bug for tracking, as you requested (https://bugs.adobe.com/jira/browse/FXU-153).

What is the best security package for an imac using yosimity

What is the best security package for an imac using Yosimity

Mac users often ask whether they should install "anti-virus" software. The answer usually given on ASC is "no." The answer is right, but it may give the wrong impression that there is no threat from what are loosely called "viruses." There is a threat, and you need to educate yourself about it.
1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to take control of it remotely. That threat is in a different category, and there's no easy way to defend against it.
The comment is long because the issue is complex. The key points are in sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
☞ It can easily be disabled or overridden by the user.
☞ A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
Apple has taken far too long to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. Those lapses don't involve App Store products, however.
For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is a problem of human behavior, not machine behavior, and no technological fix alone is going to solve it. Trusting software to protect you will only make you more vulnerable.
The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and Internet criminals. If you're better informed than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
Software from an untrustworthy source
☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software. A genuine alert that Flash is outdated and blocked is shown on this support page. Follow the instructions on the support page in that case. Otherwise, assume that the alert is fake and someone is trying to scam you into installing malware. If you see such alerts on more than one website, ask for instructions.
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Rogue websites such as Softonic, Soft32, and CNET Download distribute free applications that have been packaged in a superfluous "installer."
☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
Software that is plainly illegal or does something illegal
☞ High-priced commercial software such as Photoshop is "cracked" or "free."
☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission. All "YouTube downloaders" are in this category, though not all are necessarily malicious.
Conditional or unsolicited offers from strangers
☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
☞ You win a prize in a contest you never entered.
☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
☞ A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
☞ Anything online that you would expect to pay for is "free."
Unexpected events
☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
☞ You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a padlock icon in the address bar when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" (AV) or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
Why shouldn't you use commercial AV products?
☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
☞ Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
☞ By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
☞ Most importantly, a false sense of security is dangerous.
8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It can be as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

How to use non default port 1521 while 11.2.0.1 grid upgrade to 11.2.0.2

Hi Team ,
We are planning 11.2.0.1 Grid infra rolling upgrade to 11.2.0.2 with out any downtime.
But while up gradation due to default scan port 1521 , 11.2.0.1 databases are not able to connect (remote connections)
We are using 1900 port for existing 11.2.0.1 grid infra scan.
While up gradation it is taking default port of 1521 insted of existing port 1900.
Please provide the solution to use non default port while 11.2.0.2 up gradation.
After upgrade the status as below.
grdoratst104:/apps/grid/grdhome:+ASM4> srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1521
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1521
Here I was getting TNS:no Listener errors from the client connections.
I have modifyed the scan port then it is working fine.
grdoratst104:/apps/grid/grdhome:+ASM4> srvctl modify scan_listener -p TCP:1800
grdoratst104:/apps/grid/grdhome:+ASM4> srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1800
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1800
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1800
grdoratst104:/apps/grid/grdhome:+ASM4>
Here the problem is we need to do the grid infra upgrade with out downtime,but due this default port issue clients are not able to connect to the database.
Thanks

Why are you using a non default port? It does not improve security. It makes network management more complex. And causes the type of issues that you are facing now.
So before changing defaults, make sure that your reasons are technically sound. And using port 1900 when 1521 is available, is not technically sound by any means.
As for addressing the problem you have created for yourself by mucking around with port numbers. Use a NAT firewall (on each RAC node) to rewrite packets headers received on port 1900 and send these to the server's port 1521 instead (on the VIP or static IP as required).
This can be fairly easily done using iptables if your o/s is Linux. You need to:
a) create a pre-routing NAT rule
b) create a post-routing NAT rule
c) create a forwarding filter rule for port 1900/tcp
d) create an input filter rule to accept traffic on 1900/tcp
