Abstract
硬式編碼的 HMAC 金鑰可能會導致無法輕易修正的系統安全性問題。
Explanation
將 HMAC 金鑰硬式編碼絕對不是個好方法。HMAC 的加密強度取決於秘密金鑰的保密性,該秘密金鑰用於計算和驗證訊息驗證值。將 HMAC 金鑰硬式編碼,會讓擁有來源存取權的任何人都能檢視它,因此會減弱函數的加密強度。
範例 1:下列程式碼使用硬式編碼的金鑰來計算 HMAC:

...
DATA: lo_hmac TYPE Ref To cl_abap_hmac,
Input_string type string.

CALL METHOD cl_abap_hmac=>get_instance
EXPORTING
if_algorithm = 'SHA3'
if_key = 'secret_key'
RECEIVING
ro_object = lo_hmac.

" update HMAC with input
lo_hmac->update( if_data = input_string ).

" finalise hmac
lo_digest->final( ).

...


此程式碼能夠順利執行,但有程式碼存取權的任何人都可以存取 HMAC 金鑰。程式發佈後,除非修補此程式,否則可能無法變更硬式編碼的 HMAC 金鑰「secret_key」。若不懷好意的員工有此資訊的存取權,可能會使用此資訊來危害 HMAC 函數。

範例 1:下列程式碼使用硬式編碼的金鑰來計算 HMAC:

...
private static String hmacKey = "lakdsljkalkjlksdfkl";
byte[] keyBytes = hmacKey.getBytes();
...
SecretKeySpec key = new SecretKeySpec(keyBytes, "SHA1");
Mac hmac = Mac.getInstance("HmacSHA1");
hmac.init(key);
...


此程式碼能夠順利執行,但有程式碼存取權的任何人都可以存取 HMAC 金鑰。程式發佈後,除非修補此程式,否則可能無法變更硬式編碼的 HMAC 金鑰「hmacKey」。若不懷好意的員工有此資訊的存取權,可能會使用此資訊來危害 HMAC 函數。

Abstract
硬式編碼的 HMAC 金鑰可能會導致無法輕易修正的系統安全性問題。
Explanation
將 HMAC 金鑰硬式編碼絕對不是個好方法。HMAC 的加密強度取決於秘密金鑰的保密性,該秘密金鑰用於計算和驗證訊息驗證值。將 HMAC 金鑰硬式編碼,會讓擁有來源存取權的任何人都能檢視它,因此會減弱函數的加密強度。
範例 1:下列程式碼使用硬式編碼的金鑰來計算 HMAC:

...
digest = OpenSSL::HMAC.digest('sha256', 'secret_key', data)
...


此程式碼能夠順利執行,但有程式碼存取權的任何人都可以存取 HMAC 金鑰。程式發佈後,除非修補此程式,否則可能無法變更硬式編碼的 HMAC 金鑰「secret_key」。若不懷好意的員工有此資訊的存取權,可能會使用此資訊來危害 HMAC 函數。

Abstract
硬式編碼密碼用於從密型金鑰衍生函數 (PBKDF) 產生金鑰。若將硬式編碼密碼提供給 PBKDF,可能會導致無法輕易修正的系統安全性問題。
Explanation
將空白值做為密碼引數傳遞給以密碼為基礎的金鑰衍生函數 (PBKDF) 絕對不是個好方法。在此情況下,衍生金鑰將完全以提供的 Salt 為基礎 (使其明顯安全性較低),且會極難修正問題。產生違反規則的程式碼以後,除非修補軟體,否則通常無法變更空白密碼。如果根據空白密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將硬式編碼值做為密碼引數傳遞到加密 PBKDF:


...
Rfc2898DeriveBytes rdb = new Rfc2898DeriveBytes("password", salt,100000);
...


不僅任何有程式碼存取權的人都能夠確定這會根據 Hardcoded Password 引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 Hardcoded Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Hardcoded Password。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Hardcoded Password 的使用證據。

Abstract
硬式編碼密碼用於從密型金鑰衍生函數 (PBKDF) 產生金鑰。若將硬式編碼密碼提供給 PBKDF,可能會導致無法輕易修正的系統安全性問題。
Explanation
切勿將硬式編碼值做為密碼引數傳遞到以密碼為基礎的加密金鑰衍生函數 (PBKDF):在此情況下,產生的衍生金鑰大多將以提供的 Salt 為基礎 (使其安全性明顯降低),並且極難修正問題。產生違反規則的程式碼以後,除非修補軟體,否則通常無法變更硬式編碼的密碼。如果根據硬式編碼的密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將硬式編碼值做為密碼引數傳遞到加密 PBKDF:


...
var encryptor = new StrongPasswordEncryptor();
var encryptedPassword = encryptor.encryptPassword("password");
...


不僅任何有程式碼存取權的人都能夠確定這會根據 Hardcoded Password 引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 Hardcoded Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Hardcoded Password。若員工有此資訊的存取權,可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Hardcoded Password 的使用證據。

CCKeyDerivationPBKDF(kCCPBKDF2,
"secret",

salt,
saltLen
kCCPRFHmacAlgSHA256,
100000,

...


不僅任何有程式碼存取權的人都能夠確定這會根據 Hardcoded Password 引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 Hardcoded Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Hardcoded Password。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Hardcoded Password 的使用證據。

Abstract
硬式編碼密碼用於從密型金鑰衍生函數 (PBKDF) 產生金鑰。若將硬式編碼密碼提供給 PBKDF,可能會導致無法輕易修正的系統安全性問題。
Explanation
切勿將硬式編碼值做為密碼引數傳遞到以密碼為基礎的加密金鑰衍生函數 (PBKDF):在此情況下,產生的衍生金鑰大多將以提供的 Salt 為基礎 (使其安全性明顯降低),並且極難修正問題。產生違反規則的程式碼以後,除非修補軟體,否則通常無法變更硬式編碼的密碼。如果根據硬式編碼的密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將硬式編碼值做為密碼引數傳遞到加密 PBKDF:


...
$zip = new ZipArchive();
$zip->open("test.zip", ZipArchive::CREATE);
$zip->setEncryptionIndex(0, ZipArchive::EM_AES_256, "hardcodedpassword");
...


任何有權存取該程式碼的人,都可以判斷出它會根據硬式編碼密碼引數產生一或多個加密金鑰。此外,任何擁有基本破解技巧的人,都可以成功存取受違反規定之金鑰保護的任何資源。如果攻擊者還能存取用於根據 Hardcoded Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Hardcoded Password。若員工有此資訊的存取權,可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Hardcoded Password 的使用證據。

Abstract
硬式編碼密碼用於從密型金鑰衍生函數 (PBKDF) 產生金鑰。若將硬式編碼密碼提供給 PBKDF,可能會導致無法輕易修正的系統安全性問題。
Explanation
切勿將硬式編碼值做為密碼引數傳遞到以密碼為基礎的加密金鑰衍生函數 (PBKDF):在此情況下,產生的衍生金鑰大多將以提供的 Salt 為基礎 (使其安全性明顯降低),並且極難修正問題。產生違反規則的程式碼以後,除非修補軟體,否則通常無法變更硬式編碼的密碼。如果根據硬式編碼的密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將硬式編碼值做為密碼引數傳遞到加密 PBKDF:


...
key = OpenSSL::PKCS5::pbkdf2_hmac('password', salt, 100000, 256, 'SHA256')
...


不僅任何有程式碼存取權的人都能夠確定這會根據 Hardcoded Password 引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 Hardcoded Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Hardcoded Password。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Hardcoded Password 的使用證據。

Abstract
Null 加密金鑰會導致無法輕易修正的安全性問題。
Explanation
使用 null 加密金鑰絕不是明智的想法,因為這不僅會明顯降低卓越加密演算法提供的保護,還會使修正問題變得極為困難。產生違反規則的程式碼以後,除非修補軟體,否則無法變更 null 加密金鑰。如果 null 加密金鑰保護的帳戶出現問題,系統的所有者將必須在安全性和可行性之間做出選擇。

範例 1:以下程式碼會使用 null 加密金鑰執行 AES 加密:


...
var encryptionKey:ByteArray = null;
...
var aes.ICipher = Crypto.getCipher("aes-cbc", encryptionKey, padding);
...


不僅是任何有程式碼存取權的人員可以判斷是否使用 null 加密金鑰,甚至是任何具有基本破解技術的人都很有可能成功解密任何加密的資料。應用程式發佈後,除非修補軟體,否則無法變更 null 加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 加密金鑰的使用證據。

Abstract
Null 加密金鑰會導致無法輕易修正的安全性問題。
Explanation
使用 null 加密金鑰絕對不是個好方法。使用 null 加密金鑰不僅會明顯降低良好的加密演算法提供的保護,還會使修正問題變得極為困難。產生違反規則的程式碼以後,除非修補軟體,否則無法變更 null 加密金鑰。如果 null 加密金鑰保護的帳戶出現問題,系統的所有者將必須在安全性和可行性之間做出選擇。

範例 1:以下程式碼使用 null 加密金鑰:


...
char encryptionKey[] = null;
...


不僅是任何有程式碼存取權的人員可以判斷是否使用 null 加密金鑰,甚至是任何具有基本破解技術的人都很有可能成功解密任何加密的資料。程式發佈後,除非修補軟體,否則無法變更 null 加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 加密金鑰的使用證據。

Abstract
Null 加密金鑰會導致無法輕易修正的安全性問題。
Explanation
使用 null 加密金鑰絕不是明智的想法,因為這不僅會明顯降低卓越加密演算法提供的保護,還會使修正問題變得極為困難。產生違反規則的程式碼以後,除非修補軟體,否則無法變更 null 加密金鑰。如果 null 加密金鑰保護的帳戶出現問題,系統的所有者將必須在安全性和可行性之間做出選擇。

範例 1:以下程式碼會使用 null 加密金鑰執行 AES 加密:


...
var crypto = require('crypto');
var encryptionKey = null;
var algorithm = 'aes-256-ctr';
var cipher = crypto.createCipher(algorithm, encryptionKey);
...


不僅是任何有程式碼存取權的人員可以判斷是否使用 null 加密金鑰,甚至是任何具有基本破解技術的人都很有可能成功解密任何加密的資料。應用程式發佈後,除非修補軟體,否則無法變更 null 加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 加密金鑰的使用證據。

Abstract
Null 加密金鑰會導致無法輕易修正的安全性問題。
Explanation
null 指定給加密金鑰變數是不當的做法,因為會讓敏感與加密資訊暴露給攻擊者。使用 null 加密金鑰不僅會明顯降低良好的加密演算法提供的保護,還會使修正問題變得極為困難。產生違反規則的程式碼以後,除非修補軟體,否則無法變更 null 加密金鑰。如果 null 加密金鑰保護的帳戶出現問題,系統的所有者將必須在安全性和可行性之間做出選擇。

範例 1:以下程式碼會將加密金鑰變數初始化為 null


...
$encryption_key = NULL;

$filter = new Zend_Filter_Encrypt($encryption_key);

$filter->setVector('myIV');

$encrypted = $filter->filter('text_to_be_encrypted');

擁有程式碼存取權的任何人均可以判斷是否使用 null 加密金鑰,且採用甚至是基本破解技術的任何人都很有可能成功解密任何加密的資料。程式發佈後,除非修補軟體,否則無法變更 null 加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 加密金鑰的使用證據。

Abstract
Null 加密金鑰會導致無法輕易修正的安全性問題。
Explanation
使用 null 加密金鑰絕不是明智的想法,因為這不僅會明顯降低卓越加密演算法提供的保護,還會使修正問題變得極為困難。產生違反規則的程式碼以後,除非修補軟體,否則無法變更 null 加密金鑰。如果 null 加密金鑰保護的帳戶出現問題,系統的所有者將必須在安全性和可行性之間做出選擇。



不僅是任何有程式碼存取權的人員可以判斷是否使用 null 加密金鑰,甚至是任何具有基本破解技術的人都很有可能成功解密任何加密的資料。應用程式發佈後,除非修補軟體,否則無法變更 null 加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 加密金鑰的使用證據。

Abstract
Null 加密金鑰會導致無法輕易修正的安全性問題。
Explanation
None 指定給加密金鑰變數是不當的做法,因為會讓敏感與加密資訊暴露給攻擊者。使用 null 加密金鑰不僅會明顯降低良好的加密演算法提供的保護,還會使修正問題變得極為困難。產生違反規則的程式碼以後,除非修補軟體,否則無法變更 null 加密金鑰。如果 null 加密金鑰保護的帳戶出現問題,系統的所有者將必須在安全性和可行性之間做出選擇。

範例 1:以下程式碼會將加密金鑰變數初始化為 null

...
from Crypto.Ciphers import AES
cipher = AES.new(None, AES.MODE_CFB, iv)
msg = iv + cipher.encrypt(b'Attack at dawn')
...


擁有程式碼存取權的任何人均可以判斷是否使用 null 加密金鑰,且採用甚至是基本破解技術的任何人都很有可能成功解密任何加密的資料。程式發佈後,除非修補軟體,否則無法變更 null 加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 加密金鑰的使用證據。

Abstract
Null 加密金鑰會導致無法輕易修正的安全性問題。
Explanation
使用 null 加密金鑰絕對不是個好方法。使用 null 加密金鑰不僅會明顯降低良好的加密演算法提供的保護,還會使修正問題變得極為困難。產生違反規則的程式碼以後,除非修補軟體,否則無法變更 null 加密金鑰。如果 null 加密金鑰保護的帳戶出現問題,系統的所有者將必須在安全性和可行性之間做出選擇。

範例 1:以下程式碼會使用 null 加密金鑰執行 AES 加密:


...
CCCrypt(UInt32(kCCEncrypt),
UInt32(kCCAlgorithmAES128),
UInt32(kCCOptionPKCS7Padding),
nil,
0,
iv,
plaintext,
plaintext.length,
ciphertext.mutableBytes,
ciphertext.length,
&numBytesEncrypted)
...


不僅是任何有程式碼存取權的人員可以判斷是否使用 null 加密金鑰,甚至是任何具有基本破解技術的人都很有可能成功解密任何加密的資料。程式發佈後,除非修補軟體,否則無法變更 null 加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 加密金鑰的使用證據。

Abstract
根據 null 密碼產生並使用加密金鑰時,可能會導致無法輕易修正系統安全性的問題。
Explanation
null 值做為密碼引數傳遞給以密碼為基礎的加密金鑰衍生函數絕對不是個好方法。在此情況下,產生的衍生金鑰將完全以提供的 Salt 為基礎 (使其明顯安全性較低),且會極難修正問題。違反規則的程式碼產生之後,除非修補軟體,否則通常無法變更 null 密碼。如果根據 null 密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將 null 值做為密碼引數傳遞到以密碼為基礎的加密金鑰衍生函數:


...
var encryptor = new StrongPasswordEncryptor();
var encryptedPassword = encryptor.encryptPassword(null);
...


不僅任何有程式碼存取權的人都能夠確定這會根據 null 密碼引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 null 密碼產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則不能變更 null 密碼。若員工有此資訊的存取權,可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 密碼的使用證據。

Abstract
根據 null 密碼產生並使用加密金鑰時,可能會導致無法輕易修正系統安全性的問題。
Explanation
null 值做為密碼引數傳遞給以密碼為基礎的加密金鑰衍生函數絕對不是個好方法。在此情況下,產生的衍生金鑰將完全以提供的 Salt 為基礎 (使其明顯安全性較低),且會極難修正問題。違反規則的程式碼產生之後,除非修補軟體,否則通常無法變更 null 密碼。如果根據 null 密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將 null 值做為密碼引數傳遞到以密碼為基礎的加密金鑰衍生函數:


...
CCKeyDerivationPBKDF(kCCPBKDF2,
nil,
0,
salt,
saltLen
kCCPRFHmacAlgSHA256,
100000,
derivedKey,
derivedKeyLen);
...


不僅任何有程式碼存取權的人都能夠確定這會根據 null 密碼引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 null 密碼產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則不能變更 null 密碼。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 密碼的使用證據。

Abstract
Kubernetes API 伺服器接受匿名要求。
Explanation
如果要求沒有遭到其他已設定之驗證方法的拒絕,則 Kubernetes API 伺服器預設會接受匿名要求。由於 API 伺服器是叢集的中央管理實體,所以攻擊者可使用匿名要求來存取保護不足和安全性敏感的服務 API。

範例 1:以下組態將啟動一部 Kubernetes API 伺服器,並透過設定 --anonymous-auth=true 旗標來允許匿名要求。

containers:
- command:
- kube-apiserver

Abstract
Kubelet 組態會阻止 Kubelet 設定 iptables。
Explanation
依預設,Kubelet 會根據 Pod 組態中的網路選項,自動對 iptables 進行必要變更。在 Kubelet 組態中,將 makeIPTablesUtilChains 設定為 enabled:false 可阻止 Kubelet 管理容器與環境其餘部分之間的網路流量。這會造成 Kubelet 無法強制執行必要的網路安全性需求,也無法設定容器所要求的連線。

範例 1:以下 Kubelet 組態會阻止 Kubelet 對 iptables 進行必要變更,這是因為設定了 makeIPTablesUtilChains: false

apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
makeIPTablesUtilChains: false

Abstract
某個 Kubernetes 元件洩漏系統資訊。
Explanation
如果啟用剖析,元件將透過 Web 介面提供效能指標。效能指標顯示的資訊有助於攻擊者建立攻擊計畫。不是啟動元件的指令中不存在 --profiling 旗標,就是該旗標設定為 true

Abstract
避免使用 Kubernetes 預設命名空間。
Explanation
Kubernetes 命名空間會將一個叢集劃分為多個可管理的區塊。命名空間為名稱提供了一個範圍,簡化將各種原則指定給叢集子區段。依預設,Kubernetes 會將資源配置給 default 命名空間。使用非預設命名空間的其他命名空間可以降低錯誤或惡意活動的影響。

範例 1:以下組態將資源的命名空間設定為 default

kind: ...
metadata:
...
namespace: default

Abstract
容器化應用程式可以寫入容器的主機檔案系統。
Explanation
依預設,Kubernetes 容器執行階段會阻止應用程式寫入容器的根檔案系統。readOnlyRootFilesystem: false 設定會停用此限制,進而允許攻擊者竄改本機檔案系統或將惡意可執行檔寫入磁碟。

範例 1:以下資訊清單將 readOnlyRootFilesystem 欄位設定為 false,這會允許容器內的應用程式將資料寫入本機磁碟。

...
kind: Pod

Abstract
Kubernetes API 伺服器中未啟用 AlwaysPullImages 准入控制器。
Explanation
從登錄中提取容器映像時,通常需要授權。然而,Kubernetes 節點會快取之前啟動的容器的所有映像。攻擊者可透過啟動具有快取映像的容器來規避必要的授權。AlwaysPullImages 准入控制器可以防止這種規避。

範例 1:以下組態將啟動一部 Kubernetes API 伺服器,而 --enable-admission-plugins 旗標中沒有 AlwaysPullImages 准入控制器。

kind: Pod
...
spec:
containers:
- command:
- kube-apiserver
...
- --enable-admission-plugins=PodNodeSelector,LimitRanger

Abstract
Kubernetes API 伺服器未設定使用任何准入控制器。
Explanation
准入控制器會驗證和自訂對 Kubernetes API 伺服器的要求。准入控制器可以實施安全性控制,例如拒絕未經授權的特權要求、強制命名空間隔離、限制過多的資源要求等等。API 伺服器不會驗證要求,因為沒有准入控制器或啟用了已棄用的 AlwaysAdmit 准入控制器。

範例 1:以下組態將使用 AlwaysAdmit 准入控制器來啟動一部 Kubernetes API 伺服器。

kind: Pod
...
spec:
containers:
- command:
- kube-apiserver
...
- --enable-admission-plugins=AlwaysAdmit,PodSecurityPolicy

Abstract
組態定義一個存取權限過寬的網路規則。
Explanation
寬鬆的存取組態會將系統暴露在外,並擴大組織的受攻擊面。開放與公眾互動的服務通常會受到惡意實體近乎連續的掃描和探測。

在發現並發佈針對公開服務的零時差攻擊 (例如 Heartbleed) 時問題特別大。攻擊者可主動追蹤和搜尋未修補和暴露的系統以進行攻擊。
